Full-frame cameras are the best of the best: they have the largest sensors, the most megapixels, and lenses that are simply unmatched. Despite the size and cost, they are the go-to choice among enthusiasts and top professional photographers. In addition to DSLRs, which have long dominated the market, Sony's popular a7 series of full-frame mirrorless cameras are lighter and more compact, and Nikon and Canon recently followed suit. Below we pick the best full-frame cameras of 2018, from top all-rounders and specialty models to leading budget options. For more background information, see our full-frame camera comparison table and buying advice below the picks. 
 

Best Overall Full-Frame Camera 

1. Sony Alpha a7R III ($2,998)

Sony Alpha a7R III full frame cameraCategory: Mirrorless
Megapixels: 42.4
Weight: 23.2 oz.
What we like: Excellent image and video quality in a compact and easy-to-use package. 
What we don’t: Some may prefer an optical viewfinder. 
Lenses: 10 Great Sony FE (Full Frame) Lenses

The competition has been fierce at the top of this list, with both Nikon and Canon holding the podium for various stretches. And while Sony's previous a7R II  wasn't quite there, we think the third rendition is the top full-frame camera on the market in 2018. The Sony a7R III is the whole package: you get 42.4 megapixels of resolution, in-body image stabilization, shooting speeds up to 10 frames per second, 4K video, and fast autofocus with touch functionality. Further, Sony more than doubled the battery life with the new FZ100, which was the Achilles Heel of the older model. Mirrorless still can't compete with DSLRs in this regard, but the gap is tightening. 

We have used the Sony a7R III as our primary camera for nearly a year and have come away extremely impressed. It's packed with features, easy to use, and Sony's collection of FE lenses is becoming very competitive with the likes of Nikon and Canon (perhaps not in volume, but in quality). One of the biggest reasons to choose a DSLR like the Nikon D850 below is the optical viewfinder—many professionals just can't fathom using an electronic viewfinder all day every day, and that's a real hurdle to get over. But given the premium image and video quality and feature set, the mirrorless a7R III is our top choice. For those looking to save, the a7 III (no "R") below is $1,000 cheaper and has many of the same features but with fewer megapixels at 24.2.

Best Full-Frame DSLR

2. Nikon D850 ($3,297)

Nikon D850 full-frame cameraCategory: DSLR
Megapixels: 45.7
Weight: 32.3 oz.
What we like: Superior autofocus. 
What we don’t: Bulkier and heavier than the Sony a7R III below. 
Lenses: 10 Great Nikon FX (Full Frame) Lenses

If you're in the market for a full-frame DSLR, it's hard to argue against the Nikon D850. Simply put, this camera beats out the Canon 5D Mark IV below in most relevant categories. To name a handful, the D850 has a whopping 45.7 megapixels of resolution vs. 30.4 on the 5D Mark IV, superior autofocus, faster buffering speeds, a higher resolution LCD screen, and significantly longer battery life. The 5D Mark IV does weigh slightly less and has built-in GPS, but given that both cameras are similar in price, we favor the D850 in a big way.

We hemmed and hawed about whether to rank the mirrorless Sony a7R III over the Nikon D850 on this list—both are top-notch full-frame cameras in just about every way. For professionals who use their camera every day, the optical viewfinder on the D850 often is a deciding factor, along with the collection of full-frame lenses they likely already own. And while Sony has dramatically improved the autofocus capabilities of their cameras, the D850 still is superior in this regard. Having said that, all signs point to mirrorless being a big part of the future of photography, so much so that Nikon just released two full-frame mirrorless cameras: the Z6 and Z7 below.

Best Budget Full-Frame Camera

3. Canon EOS 6D Mark II ($1,599)

Canon 6D Mark II DSLR cameraCategory: DSLR
Megapixels: 26.2
Weight: 24.2 oz.
What we like: A great value for a full-frame camera. 
What we don’t: Video shooters may want to spend up for the 5D series.
Lenses: 10 Great Canon EF (Full Frame) Lenses

We have been fans of Canon's 6D series for years, which represents an affordable entry point into the full-frame market from one of the best in the business. Last year, Canon released the 6D Mark II, which offers notable improvements over its predecessor while still staying well below the $2,000 threshold. Compared to the older model, you get a bump in resolution to 26.2 megapixels, a more advanced autofocus system, faster shooting, and touchscreen functionality on the rear LCD. All are solid improvements and make the 6D Mark II a really nice value, particularly for still photography (the 5D series admittedly is much better for video).

The biggest competitor to the Canon 6D Mark II is the Nikon D750 below. Both have similar resolutions (the 6D Mark II is slightly better in this regard with 2 more megapixels) and burst rates (6.5 frames per second), but the Canon feels more modern with its touchscreen, Bluetooth and NFC connectivity, and newer processor. And it should: the Nikon D750 was released all the way back in 2014 with no word yet on a successor. If you're considering going mirrorless, the Sony a7 III below is a fun camera that also is reasonably priced. 
See the Canon EOS 6D Mark II

 

Best of the Rest

4. Canon EOS 5D Mark IV ($3,099)

Canon 5D Mark IV full-frame cameraCategory: DSLR
Megapixels: 30.4
Weight: 28.2 oz.
What we like: Does everything well. 
What we don’t: Fewer megapixels and features than the Nikon D850 above.
Lenses: 10 Great Canon EF (Full Frame) Lenses

For non-action shooters, the 5D Mark IV is Canon's leading full-frame DSLR and is loaded with functionality. This popular camera comes with big improvements over the older 5D Mark III including a jump in resolution to 30.4 megapixels, 4K video, and a faster burst rate at 7 frames per second. A notable plus in going with a pro-level Canon camera is the amazing color rendering and skin tones that the brand is known for. For everyone from professional photographers to enthusiasts, the 5D continues to be one of the top DSLRs on the market, period.

The Canon 5D Mark IV, however, is in many ways outmatched by the Nikon D850. As described above, the Nikon wins out in most categories that matter: it has more megapixels, superior autofocus, a more modern feature set, and both cameras are similarly priced. Given that most professionals choose one brand and stick with it (it's not easy or cheap to switch out an entire collection of lenses), the 5D Mark IV is more than enough camera for most people. And new for the 2018 holiday season, Canon's long-awaited EOS R has been dubbed the mirrorless version of the 5D Mark IV, which certainly is an exciting development.

5. Sony Alpha a7 III ($1,998)

Sony a7 III full frame cameraCategory: Mirrorless
Megapixels: 24.2
Weight: 22.9 oz.
What we like: A more affordable way to access Sony’s popular a7 series.
What we don’t: Lower resolution than the a7R III.
Lenses: 10 Great Sony FE (Full Frame) Lenses

We'll start by saying that we really like what Sony has done with the Alpha a7 III, which was released in 2018. This camera incorporates many features from the popular a7R III above, including a fast burst rate of 10 frames per second, 4K video functionality, and the FZ100 battery that more than doubles the number of photos you can take compared to the older a7 II. While the a7R III is totally capable of shooting action, the a7 III actually is better in this regard with 693 autofocus points compared to the 399 on the a7R III. And at just under $2,000, it's a reasonably-priced way to access to Sony's full-frame camera lineup without sacrificing a ton in the way of performance.

What are the shortcomings of the Sony a7 III? Most notably, the camera has a 24-megapixel sensor, which represents a considerable drop from the 42.4 megapixels of the a7R III. However, for many people—and particularly non-professionals who won't be enlarging their prints to epic proportions—this is ample resolution and can create outstanding images and videos. And an upside to the image size is that processing photos will be faster as your computer won't be bogged down by the massive files. All in all, similar to the Canon 6D Mark II and Nikon D750, the a7 III can be everything you need in a full-frame camera and nothing you don't.

6. Nikon D750 ($1,697)

Nikon D750 full-frame cameraCategory: DSLR
Megapixels: 24.3
Weight: 26.5 oz.
What we like: A sub-$1,700 full-frame camera from one of the best in the business.
What we don't: Lower resolution than the D850 and has an optical low pass filter. 
Lenses: Best Lenses for Nikon D750

Nikon had a rough start with its "budget" full-frame DSLR line: both the Nikon D610 and D600 had sensor spotting issues that were tough to overcome. The good news is that the D750 is the real deal and one of the best values on this list. For less than $1,700, you get a full-frame image sensor with 24 megapixels of resolution, good weather sealing, and reasonably fast shooting speeds at 6.5 frames per second. Despite being released all the way back in 2014, it's telling that the D750 is one of the oldest models on this list yet still sits at #6. Simply put, it's more than enough camera for many people at a very reasonable price point.

It's interesting that Nikon hasn't yet announced a successor to the popular D750. The company certainly has been focusing on its new full-frame mirrorless system including the Z7 below, but the D750 is missing some important features that people have come to expect in 2018. For example, the camera lacks image stabilization, touchscreen functionality, and does not shoot 4K video. But most of the other components are there, including great image quality for the price and access to Nikon's vast collection of full-frame lenses. For still shooters on a budget, the D750 still is a very nice choice. 
See the Nikon D750

 

7. Canon EOS 5DS R ($3,699)

Canon EOS 5DS R cameraCategory: DSLR
Megapixels: 50.6
Weight: 29.7 oz.
What we like: The highest resolution camera on the full-frame market. 
What we don’t: High price tag and lack of video options. 
Lenses: 10 Great Canon EF (Full Frame) Lenses

In the full-frame arms race, Canon took a big step forward with the 5DS R. Most impressive is the 50.6 megapixels of resolution, which surpasses the 5D Mark IV by 20.2 megapixels and even tops the Nikon D850 and Sony a7R III. It's worth noting that this camera bucks the hybrid trend and is designed primarily for still photography without video-centric features like headphone sockets or an HDMI output. And keep in mind that Canon released two slightly different versions of this camera: the 5DS (no "R") drops the optical low pass filter and costs $200 less. Both are phenomenal cameras for professional landscape and portrait photographers who don't need the speed or video capabilities of the other full-frame cameras above. 

However, there are some downsides to consider here, and the 5DS R may not be quite as ideal as its 50.6 megapixels suggest. To start, it's not an amazing low light performer and doesn't have quite the dynamic range of a camera like the Sony a7R III. Pair that with the relatively slow 5 frames per second of shooting speed, and it's not nearly as good of an action camera either. But if you're a Canon shooter in the hunt for medium format-like resolutions, the 5DS R is as close as you'll get. Other options include going with the a7R III with an adaptor for Canon glass, and on the other side of the aisle, the Nikon D850 above is well worth a look at 45.7 megapixels.
See the Canon EOS 5DS R

 

8. Nikon Z7 ($3,397)

Nikon Z7 mirrorless cameraCategory: Mirrorless
Megapixels: 45.7
Weight: 20.6 oz.
What we like: A true competitor to Sony right out of the gates. 
What we don't: Currently there are only three Z-mount lenses to choose from. 

Nikon came out swinging with the new Z7 and Z6 full-frame mirrorless cameras. The Z7 is the higher-resolution model of the two, featuring a 45.7-megapixel image sensor, in-body image stabilization, 4K video, and just about all of the other advanced features you would expect from a new camera at this price point. In many ways, the Z7 is very similar to the Sony a7R III above but with a better rear LCD and slightly inferior autofocus. For those looking to save, the Z6 is the lower-resolution sibling of the Z7 with a 24-megapixel sensor, but that version does boast better ISO sensitivity.

When comparing the Nikon Z7 and uber-popular Sony a7R III, perhaps the biggest difference is lens selection. Nikon's first three Z lenses are reminiscent of Sony's entry into the full-frame mirrorless market: a trio of good-but-not-great glass with limited maximum apertures: a 24-70mm f/4, 50mm f/1.8, and 35mm f/1.8. Nikon has released an impressive roadmap of Z-mount lenses that starts filling in the gaps over the next couple of years, but this system is quite limited to start. There are no true wide-angle options, for example, nor is there is an available telephoto zoom. All things considered, the camera measures up nicely, but the lenses do not (yet). It's worth noting that Nikon does make an FTZ adapter for $250 that is available on its own or in many of the Z7 and Z6 kits. 
See the Nikon Z7

 

9. Pentax K-1 Mark II ($1,897)

Pentax K-1 Mark II cameraCategory: DSLR
Megapixels: 36.4
Weight: 32.6 oz.
What we like: A nice option for outdoor photographers with good resolution and great weather sealing. 
What we don't: Mediocre autofocus and lens selection.  

It's easy to sleep on Pentax, but the brand has a loyal following among outdoor photographers who appreciate the weather sealing and value. Earlier this year, Pentax released the K-1 Mark II, which was one of the more interesting developments in the full-frame market. Yes, you only get a minuscule upgrade of .2 megapixels total, but the camera now offers an advanced pixel shift mode. Essentially, you can shoot handheld and it will combine four images into one very high-resolution file. It doesn't work perfectly and some still recommend using a tripod with pixel shift, but it's an exciting advancement and we love seeing Pentax take the leap. 

One of the biggest complaints about the original K-1 was poor autofocus tracking. While the Mark II is a step up and the autofocus is considerably more reliable, it still lags behind the competition and we wouldn't recommend going with this body if you're looking to shoot fast-moving objects. Unfortunately, Pentax also took the liberty of baking in mandatory noise reduction into higher ISO files, which we think degrades image quality straight out of the camera. Both of these aspects speak to the true intended usage of the K-1 Mark II: a rugged landscape camera meant to be used on a tripod. Out in the elements and capturing epic landscapes is where it really shines.

10. Sony Alpha a9 ($4,098)

Sony Alpha a9 full-frame cameraCategory: Mirrorless
Megapixels: 24.2
Weight: 23.7 oz.
What we like: The fastest full-frame camera on this list at 20 frames per second.
What we don’t: Sony may be cannibalizing the a9 with the impressive a7R III and a7 III above.
Lenses: 10 Great Sony FE (Full Frame) Lenses

Over the past few years, mirrorless cameras have made serious inroads in areas like resolution and video quality, but pro-level speed has remained the sole domain of DSLRs. That all changed in April of 2017 when Sony announced the new Alpha a9. At a blazing fast 20 frames per second and with an ultra-advanced 693-point phase-detection autofocus, the Sony a9 outperforms leading options from other top brands like the Canon 1DX Mark II (14 fps) and Nikon D5 (12 fps). For sports and action photography, it’s the new clubhouse leader.

There are a couple of important reasons why the Sony a9 isn't ranked higher on this list. The first is practicality: few people outside the world of action photography need anything close to 20 frames per second, and therefore a higher resolution and less expensive camera like the a7R III is a better all-around fit. Second, the full-frame lens options for Sony are growing but still lag behind Canon and Nikon, and particularly at the telephoto end of the spectrum. Given that many sports and action photographers are deeply entrenched in their lens collections, it would be very costly to make the switch. However, Sony has shown they are committed to expanding their lenses, which is demonstrated by the recent release of the 400mm f/2.8 and 100-400mm f/4.5-5.6. 
See the Sony Alpha a9

 

11. Canon EOS 1D X Mark II ($5,499)

Canon 1D X Mark II cameraCategory: DSLR
Megapixels: 20.2
Weight: 53.4 oz.
What we like: The top DSLR on the market for action photographers.
What we don’t: Hefty size, short battery life, and high price.  
Lenses: 10 Great Canon EF (Full Frame) Lenses

The Canon 1D X Mark II and Nikon D5, along with the much less-popular Sony a99 II, offer the fastest shooting speeds of any DSLRs on this list (the Sony a9 is fastest, but that's a mirrorless camera). In comparing the two heavy hitters, the Canon 1D X Mark II shoots faster at 14 frames per second instead of 12 on the D5, not to mention it costs approximately $500 less. On the other hand, the Nikon D5 has significantly better battery life and superior ISO sensitivity. Action shooters can't go wrong and both cameras are great at what they do, but we appreciate the extra speed and lower price of the 1D X Mark II. 

Why aren't either the Canon 1D X Mark II or Nikon D5 ranked higher? First, they are specialty cameras for professional action photographers and the feature sets don't appeal to the majority of people. Second, a camera like the 1D X Mark II is extremely heavy at over 53 ounces, which is nearly double the Canon 5D Mark IV at just over 30 ounces. Finally, as we've alluded to above, mirrorless cameras like the Sony a9 are changing the game in terms of resolution and shooting speeds in compact packages. Canon's new EOS R is fairly mediocre in this regard at 9 frames per second (at least for mirrorless), but Nikon's Z6 is better at 12 frames per second. Once the lenses catch up, action photography seems to be trending mirrorless. 
See the Canon EOS 1D X Mark II

 

12. Sony Alpha a99 II ($3,198)

 Sony a99 II DSLR cameraCategory: DSLR
Megapixels: 42.4
Weight: 30 oz.
What we like: Impressive specs across the board. 
What we don’t: A-mount lens options and Sony's questionable commitment to DSLRs. 

Just when many people thought Sony’s A-mount line of full-frame DSLRs was on the way out, the impressive a99 II hit the market. Released at the end of 2016 and four years after the original a99, the technological jumps were large. The a99 II has a whopping 42.4 megapixels of resolution vs. 24.3 on the old version, the camera shoots a speedy 12 fps instead of 6 fps, and you get 4K video, among a number of other features. This is an entirely different DSLR and gives heavy hitters like the Nikon D850 and Canon 5D Mark IV a run for their money.

Despite all the positives, it still feels like Sony's a7 cameras overshadow the a99 II. Much of the company's resources have gone toward developing and marketing mirrorless, and a good number of people already have settled on a7 systems (ourselves included). Further, the available A-Mount lenses fall well short of the quantity and quality for Canon or Nikon DSLRs. Sony is not abandoning the A-Mount and has said that they will be developing more lenses in the future, but it's hard to bump this camera further up this list until that comes to fruition. 
See the Sony Alpha a99 II

 

13. Nikon D5 ($6,497)

Nikon D5 cameraCategory: DSLR
Megapixels: 20.8
Weight: 49.9 oz.
What we like: Fast burst and autofocus.
What we don’t: Slower than the Canon 1D X Mark II above; too heavy and expensive for most people.
Lenses: 10 Great Nikon FX (Full Frame) Lenses

The Nikon D5 is a monster of a full-frame DSLR. With blazing speed, it’s one of the cameras you’ll see behind the basket at the NBA Finals and on the sideline of the Super Bowl. However, the D5 weighs in at over 3 pounds—all other cameras on this list aside from the Canon 1D X II above are at least a full pound less. Redeeming features are the fast burst rate of up to 12 frames per second and impressive ISO range that goes from 100-102,400. If you shoot action or sports, this is the premier Nikon DSLR on the market and worth the investment (especially if your employer is paying).

With Nikon's recent entry into the full-frame mirrorless world, it will be interesting to see how models like the D5 fare. While the two mirrorless cameras weren't built to replace the D5, the Z6 can shoot a very respectable 12 frames per second (the Z7 is slower at 9 frames per second). With the new Z mount, these cameras are limited in terms of lens options without using an adapter, but Nikon already has expressed their plans to expand the Z line pretty quickly. We aren't saying that you should replace your D5 with a Z6, but it will be fun to see how Nikon's mirrorless system evolves. 
See the Nikon D5

 

14. Nikon D810 ($2,797)

Nikon D810 full-frame DSLRCategory: DSLR
Megapixels: 36.3
Weight: 31.1 oz.
What we like: Resolution and features still are competitive.
What we don’t: At this price, we think it’s worth spending up for the D850.  
Lenses: Best Lenses for Nikon D810

For years, the D810 was Nikon’s leading full-frame camera and still is quite impressive in terms of image quality and features. Despite being released all the way back in 2014, the 36.3-megapixel sensor beats the Canon 5D Mark IV’s 30.4 megapixels, and just about everything else is competitive. The camera shoots decently fast at 5 frames per second and has a longer battery life than the 5D Mark IV and Sony’s most recent mirrorless models. If you’re not always looking for the latest and greatest, the D810 should not disappoint.

Our biggest issue with buying the Nikon D810 now is price. At a whopping $2,800, the newer Nikon D850 is only $500 more, yet you get a host of significant upgrades including a jump in megapixels, improved autofocus, 4K video, touchscreen functionality, faster shooting, a superior rear LCD, and more (we could go on and on). To us, the upgrade clearly is worth the extra cost. But if the Nikon D810 eventually drops down to the low $2,000s, that would make it a much more appealing option. 
See the Nikon D810

 

15. Leica M-P ($5,949)

Leica M-P full-frame cameraCategory: Rangefinder
Megapixels: 24
Weight: 24 oz.
What we like: Superb contrast, color rendition, and overall image quality. 
What we don't: The most expensive camera on this list, and Leica lenses aren’t exactly cheap either. 

The Leica M-P is beyond the price range of most consumers, but all things considered, it’s one of the finest cameras on the planet. When used correctly, this rangefinder is smaller and takes photographs that are on par or better than any other full-frame camera. Leica also makes some of the fastest and highest-quality lenses, a big reason why ultra-discerning photographers love the brand. 

Despite its impressive image quality, throwback feel, and compact size, there are some notable downsides to the M-P. The camera has a very limited ISO range that only stretches up to 6400, meaning that it has inferior low light capabilities compared to a more modern like the Sony a7R III, which goes up to 32000 on auto or 102400 extended. In addition, the fastest you'll be able to shoot with this camera is 3 frames per second, making action nearly impossible to capture. Finally, the camera is manually focused as a rangefinder, which will turn most photographers away who aren't familiar with this old-school technology. For the majority of shooters, a Leica is expensive and not very practical. But for those who can afford it and want a rangefinder, the precision and lenses are unmatched.
See the Leica M-P

 

16. Nikon Df ($2,747)

Nikon Df cameraCategory: DSLR
Megapixels: 16.2
Weight: 25 oz.
What we like: Classic styling and durable metal build.
What we don't: A fun camera, but not a great value based on specs.
Lenses: 10 Great Nikon FX (Full Frame) Lenses

The Nikon Df is a very cool concept: a metal full-frame DSLR with a focus on manual controls. Impressively, the Df is Nikon’s lightest full-frame camera outside of the new Z7 at around 25 ounces, has the same image sensor as the high-end D4, and is fully compatible with Nikon’s wide selection of FX lenses. And we love the classic design, which is reminiscent of Fujifilm.

The Df remains a specialty camera for a number of reasons. First, it has lower resolution than other Nikon cameras at a very pedestrian 16.2 megapixels. Second, despite the small form factor, the metal components make it decently heavy for its size. Third, the Df is expensive at nearly $3,000 (for comparison, the D750 is more than $1,000 cheaper but clearly wins out in the specs department). All things considered, this may not be a workhorse camera for professional photographers with an eye on the bottom line, but it does make a nice collector's item for those who love the classic look and feel.

17. Leica SL ($5,995)

Leica SL mirrorless cameraCategory: Mirrorless
Megapixels: 24
Weight: 29.9 oz.
What we like: Leica image quality is tough to beat.
What we don’t: Nearly double the price of the Sony a7R III.

A few years ago, Leica released the SL, which represented their first foray into mirrorless. Sony was long overdue for a challenge, but we didn't expect it to first come from rangefinder-specialist Leica. On paper, the SL is impressive: a 24-megapixel full-frame image sensor, 4K video, an ultra-high resolution electronic viewfinder, and a fast burst rate of 11 frames per second (for comparison, the a7R III shoots 10 frames per second). You also get a nifty top-mounted LCD display.

Coming in at nearly double the price of the a7R III, the real question is whether the SL merits the cost. People like to say that you're paying extra for the little red "Leica" badge on the camera, and while you do get some nice features and access to incredible glass, we don't think that paying nearly double the price of a Sony is worth it. Granted, Leica fans will fervently argue the opposite, but if you fall into that category then you don't need convincing from us. For the rest of you, we think you're better off saving with the Sony a7R III.

18. Sony Alpha a7 ($798)

Sony a7 full-frame cameraCategory: Mirrorless
Megapixels: 24
Weight: 16.7 oz.
What we like: Cheap and light for a full-frame camera.
What we don’t: Subsequent a7 cameras have much better features and functionality. 
Lenses: 10 Great Sony FE (Full Frame) Lenses

Sony's mirrorless a7 series gets a lot of praise for being the lightest and most compact full-frame cameras on the market. But as you can see from the rather pricey models above, they are out of reach for many consumers. For this reason, we've included the oft-forgotten original Sony a7, which is selling for a bargain basement price of less than $1,000 with a 28-70mm kit lens. That's cheaper than any other camera on this list by far, and while it may be outdated, it's a viable starting point for people looking to get into full-frame photography at a low price point.

What do you sacrifice by going with the oldest generation a7? The latest Sony a7 III has built-in image stabilization, which is a really nice feature, along with better autofocus and an improved magnesium alloy body that should stand up to wear and tear better than the composite materials used here. The a7 also shoots relatively slow at 5 frames per second and utilizes Sony's older battery style, which can be a headache if you're out shooting all day. But for the price, this camera gets your foot in the door of the Sony Alpha system for less than $1,000.

Full-Frame Camera Buying Advice

Resolution

Every camera on this list has a full-frame sensor that measures approximately 36 x 24 millimeters (some are slightly less by tenths of a millimeter). But megapixels are another factor in determining overall image quality. If you plan on enlarging photographs to massive proportions, you should consider a full-frame camera with a high megapixel count like the Nikon D850, Canon EOS 5DS R, or Sony Alpha a7R III. It's true that the differences may not be discernible at many print sizes and all of the cameras above can capture professional-grade images that can be enlarged and hung on your wall. But landscape photographers and others making large prints will appreciate the difference. Keep in mind that higher resolutions do come with the need to be very precise with your focusing and other technical aspects—any weaknesses will be magnified.

Weight and Size

Weight and size didn’t used to be major factors in choosing a full-frame camera. Most digital SLRs are in the ballpark of 30 ounces and action-centric models like the Canon 1D X Mark II and Nikon D5 are even heavier. Professional photographers had a bulky camera bag and set-up and there weren’t easy ways around it. However, Sony’s a7 Series of full-frame mirrorless cameras changed the landscape, bringing the weight of the camera body closer to 20 ounces and with a much more compact form factor.

It wasn’t until the second generation and the Sony's a7R II that we noticed a critical mass of professionals making the switch to lighter mirrorless cameras. A number of people picked up an early a7 or a7R, but those cameras had enough shortcomings—and combined with the lack of lens choices—were less viable for daily work. But when Sony beefed up the megapixel count on the a7R II to 42.4, added 4K video, and reinforced the lens mount, the camera quickly became a powerhouse. At least in the world of outdoor photography, a significant number of people have made the switch to the a7 series and use it as their primary camera.

The Sony a7R III and Nikon D850

Keep in mind that with lenses included, you might not actually save all that much weight by going mirrorless. To use the standard 24-70mm f/2.8 pro zoom as an example, Sony’s version of that lens weighs in at a hefty 31.3 ounces, whereas Canon’s is only 28.4 ounces. This means that the Sony a7R III with a 24-70mm f/2.8 lens is 54.5 ounces total, while the Canon 5D Mark IV with a 24-70mm f/2.8 is 56.6 ounces. It’s true that the Sony a7R III has a smaller form factor, but the weight difference between those two set-ups is an insignificant 2.1 ounces. Mirrorless cameras are lighter, but perhaps not as much as people think. 

Both Nikon with the Z7 and Z6, and Canon with the EOS R, entered the full-frame mirrorless market in 2018, which was a big deal. While both of these cameras are much lighter than typical Nikon and Canon full-frame DSLR bodies, they run into the same problem as Sony when paired with lenses. And especially the Canon EOS R: the new RF-mount lenses tend to be even heavier than their EF counterparts. For example, the new 28-70mm f/2 comes in at a very substantial 50.4 ounces. Pair that with the EOS R, and you're looking at a set-up that weighs more than four pounds and is nearly one pound heavier than the Canon 5D Mark IV and 24-70mm f/2.8. In conclusion, while it seemed at the outset that one of the big perks of going mirrorless was saving weight, this becomes less relevant when taking lenses into account.
 

DSLRs vs. Mirrorless

For decades, digital SLRs reigned supreme in the full-frame camera world. Five years ago, along came Sony with the a7 series and things started to shift. Finally, there were full-frame camera bodies that were smaller than DSLRs yet offered comparable image quality. Granted, it took Sony awhile to work through some bugs, and we saw rapid innovations and releases in their a7 line (they have come out with eight cameras in the a7 line in the last five years). Now, with cameras like the a7R III, mirrorless has become a huge player and we've seen many professionals and enthusiasts switch from DSLRs to mirrorless. And with Nikon and Canon jumping into mirrorless for the 2018 holiday season, we expect more people to take the leap. What are the main differences between DLSRs and mirrorless cameras? We answer that question below.

Internal Mirror System (or Lack Thereof)
The most obvious difference is in the name: a mirrorless camera lacks the complex internal mirror system of a DSLR. This means that they are able to be smaller and lighter, and the absence of a mirror also means they can shoot at faster frame rates (there is no mechanism that needs to go up and down for each frame). This is why a camera like the Sony a9 is able to shoot up to 20 frames per second, whereas the Canon 1D X Mark II only goes up to 14 frames per second despite costing and weighing considerably more.

Battery Life
While mirrorless cameras do have advantages in terms of size and features, there are some notable downsides. First, there just isn't a ton of space for large batteries. Battery life (or lack thereof) has been one of the biggest complaints about mirrorless cameras, to the point where it is common to have to carry a pocket full of batteries for a long day of shooting (with a DSLR like the Nikon D850, you can only carry one battery per day). However, recent cameras like the Sony a7R III do have larger and better batteries than their predecessors, and while they still don't last as long as most DSLR cameras, we find them to be totally adequate for most people.
 
Optical vs. Electronic Viewfinders
Another big difference between these two camera styles are the viewfinders. DSLRs boast an optical viewfinder (OVF), whereas mirrorless cameras typically have electronic viewfinders (EVF). In comparing the two, an optical viewfinder shows you exactly what the lens is seeing rather than an electronic rendition, and many prefer the real-world experience of an OVF. For mirrorless enthusiasts, this is one sacrifice you just have to make.

All things considered, the choice boils down to personal preference. Some photographers prefer the compact size, superior video capabilities, and modern features that come with mirrorless, whereas others like the extended battery life, abundant lens options, and optical viewfinder that you get with a DSLR. It's also worth noting that to this point, DSLRs have much larger lens selections than mirrorless, which largely is the result of time on the market. Sony is catching up with its full-frame FE-mount options, but Nikon and Canon literally have a decades-long advantage. And it's exciting that both Nikon and Canon both made the jump to mirrorless in 2018. Competition is good for consumers and means more options for everyone. 
 

Video and 4K

Full-frame cameras are at the top of the camera heap for both still photography and video. Cameras like the Canon 5D Mark IV and Nikon D850 shoot superb video: they have excellent low light performance, highly advanced autofocus, a wide variety of frame rates, a ton of manual controls, excellent audio, and the full range of outputs. Canon traditionally has been known for superior video, but Nikon has caught up over the years and the D850 and other offerings can compete with any camera on the market.

The relatively recent emergence of 4K video resolution in full-frame cameras is again changing the status quo. Sony first offered 4K with the mirrorless a7S, a video-centric camera with only 12.2 megapixels for stills, but later added the technology to models like the a7R II, a7 III, and a99 II. Leica's new SL also offers 4K. From Canon, the EOS R, 5D Mark IV, and 1D X Mark II shoot 4K video, and for Nikon it's the Z6, Z7, D850, and D5. 4K isn't offered on every new full-frame camera (the Canon 6D Mark II, for example), but in 2018 it's the norm on mid-range and high-end cameras.

Unfortunately, keep in mind that some of the new mirrorless models like the Nikon Z7 and Canon EOS R crop down into a frame similar to an APS-C sensor when shooting 4K, meaning that you lose some focal length. But as mirrorless continues to evolve and we see the major companies putting their innovation efforts into them, we'll most likely see some impressive video specs in more mirrorless cameras in the future. 
 

Shooting Speed

Most photographers don’t need blazing fast shooting speeds, which are measured in frames per second (fps). But for action and sports, speed is a must. Interestingly, a new player has emerged on the action scene: the Sony Alpha a9. With the same general design as Sony’s popular a7 series, the a9 pushes the envelope in a big way at an impressive 20 fps. Second place in the full-frame category goes to the Canon 1DX Mark II at 14 fps, and both the Nikon D5 and Sony a99 II shoot at 12 fps. All other full-frame cameras on the list have frame rates in the range of 11 fps to 3 fps. 

The release of the a9 has opened up a lot of discussion about switching over to Sony’s full-frame system. Many professional action photographers are set with a whole bag of specialty Canon or Nikon lenses, and the prospect of selling all of those lenses and starting from scratch would be financially daunting. However, at least on paper, the a9 is indeed the top action camera (for now) and Sony’s collection of lenses is expanding quickly. We’ve really enjoyed shooting with the G Master series, and Sony recently added a 100-400mm f/4.5-5.6 GM and 400mm f/2.8 GM to the mix.

There are some sacrifices of choosing an ultra-fast camera. The first is resolution, which tends to drop as frame rates increase. For example, the Sony Alpha a9 (20 fps) is 24.2 megapixels while the a7R III (10 fps) is 42.4 megapixels. The Canon 1D X Mark II (14 fps) is 20.2 megapixels while the Canon 5D Mark IV (7 fps) is 30.4 megapixels. Second is cost: the action cameras above are the most expensive models on the market, often close to double their slower counterparts. It's a no-brainer if you're a professional action photographer who needs the fast shooting speeds, but unless your primary subjects are athletes, most people realistically don't. We've found that the shooting speeds and autofocus tracking of cameras like the Nikon D850, Sony a7R III, and Canon 5D Mark IV are great for moving subjects and will satisfy the majority of shooters.


Weather Sealing

Full-frame cameras are the best of the best, and every camera on this list is advertised as being weather sealed. Unfortunately, there isn't standardization or universal testing of weather sealing, so the way one company seals a camera may be very different from how another does. In general, the process involves covering and sealing the joints and button areas on the camera body with rubber to reduce exposure to moisture and dust. This makes the camera resistant to the elements and we've seen people shoot in some pretty tough conditions and come away unscathed, but they certainly aren't "waterproof" (even true "waterproof" cameras constantly receive complaints of leakage).

Most photographers aren't out in downpours or extreme weather for extended periods of time, and therefore should be satisfied with the sealing of the cameras on this list. In terms of differentiation, Imaging Resource conducted some fun simulated rain tests and concluded that cameras made by Canon and Nikon fared well whereas Sony cameras let in small amounts of water, especially in the battery compartment. While the camera wasn't ruined and functioned properly after a day or two of drying out, it's worth noting. And if you plan on shooting in extreme conditions, consider using a hood or taking further steps to protect your camera and lenses. 
 

Lens Cost

Don't overlook the cost of lenses when buying your camera. A full-frame sensor will expose the weaknesses of low-quality lenses, and the lens offerings are more expensive than their crop-frame siblings. For "budget" full-frame cameras like the Nikon D750 and Canon 6D Mark II, the kit lenses will allow you to start shooting photos without breaking the bank. Another strategy for saving money is to start with one quality lens for the type of photography you shoot most. Landscape photographers will want a good wide-angle lens that likely will cost from around $1,000 to $2,000. Portrait shooters can spend less as lenses like the 50mm and 85mm primes are some of the best values on the market. And the zoom options are better than ever before, which offer a nice compromise between cost and image quality.

Whatever your lens strategy is, it's a good idea to at least do a rough calculation of the total cost of your camera with lenses to avoid sticker shock. Keep in mind that acquiring lenses is a slow process and we think it's best to skip shortcuts and invest in better glass. As long as you stick within the same camera system, you'll have your lenses far longer than any camera body and making the right choices will serve you well in the long run. 
 

Choosing a Brand

Technically speaking, you can always switch brands once you buy a full-frame camera and lenses, but it's a much costlier process than with a crop-frame system. For example, many Nikon shooters have a collection of FX full-frame lenses and update camera bodies every few years, and the same goes for Canon and Sony shooters. This means that when you make a full-frame camera purchase, you likely will end up continuing on with that brand well beyond the lifespan of one camera. 

Both Nikon and Canon are highly respected brands and offer the widest selection of lenses for their DSLRs. Sony is an up-and-comer with its full-frame mirrorless offerings, but its collection of FE (full-frame) lenses is improving and gets better by the year. And now that all three major brands have full-frame mirrorless cameras and are showing signs of being committed to innovating in that realm, we anticipate seeing less photographers switching brands like they did during the mass exodus to Sony. The broader point is that whatever brand or system you choose at the outset, know that it likely will be your system for years to come.

Learning Curve

Compared to entry-level or mid-range cameras, full frame offers the most creativity and customization by far. The good news is that almost all of the models on this list have automatic shooting modes that will help you capture great photos while letting the camera do much of the work. At the same time, these high-end cameras excel at making manual adjustments to things like focus, exposure, ISO sensitivity, and white balance. You don't have to tackle them all at once, but it's a good idea to get comfortable with your camera before you depend on it for the perfect shot. Out of the box, read the manual, charge the battery, and head out for some test shoots. Particularly if you haven't used that brand before, it takes some time to become fluent with the camera and menu. 

Keep in mind that owning a full-frame camera doesn't mean that you'll always be able to capture images like those you see from the pros. Ultimately, a talented photographer or professional can make a beautiful image with any camera. It takes a lot of practice and trial and error to understand how to compose great photographs, and you may learn new tricks every time you're out in the field. A nice camera does translate to better resolution and features, but it's up to the person using it to understand all the intricacies and nuances of what it takes to capture a great image.

Full Frame vs. Medium Format

Medium format once was the exclusive territory of the most serious fine art and landscape photographers. These extremely expensive cameras have image sensors that dwarf even full frame, ranging from 53.4 x 40.0mm for a Hassalblad down to 43.8 x 32.8mm for a Pentax or Fujifilm. Given that full-frame image sensors are approximately 36 x 24mm (864 sq. mm), a Hassalblad medium format image sensor (2,136 sq. mm) is well over double the size. Combined with a whopping 100 megapixels of resolution and a $33,000 price tag, that’s one heckuva digital camera.

The reason we’ve included this section on medium format is that the technology finally has trickled down to a broader range of photographers. A couple of years ago Pentax released the 645Z medium format camera for around $7,000, and last year Fujifilm released the mirrorless GFX 50S at $5,849. What’s perhaps most interesting, however, is that Fujifilm skipped competing with Sony’s popular a7 series of full-frame mirrorless cameras altogether and went straight to medium format. This should raise at least some eyebrows that medium format may take further aim at the consumer market in the coming years.
