Best full-frame camera 2020: the 10 finest high-end DSLRs and mirrorless cameras

Looking for the best full-frame camera you can buy right now? You're certainly not short of options. In fact, there's never been a better time to buy a full-frame camera, with some superb new mirrorless and DSLR options making it a very difficult buying decision. Luckily, we're here to help you decide the best full-frame camera for you.  

What's so special about full-frame cameras? The key difference is that their sensors are much larger than the ones found in APS-C, Micro Four Thirds and compact cameras. This means there's room for larger pixels, which can gather more light and help improve image quality at higher ISO sensitivities. 

Not too long ago, full-frame cameras were the exclusive preserve of professional photographers. You also only really had two manufacturers to choose from; Canon and Nikon. That's all changed with the fast rise of full-frame mirrorless cameras, which combine that larger sensor with cutting-edge autofocus systems and more compact bodies. 

With Sony and Panasonic supplying some very strong competition for their established rivals, there is now a huge range of full-frame mirrorless cameras and DSLRs to choose from. The fast pace of change also means that there's great value to be found in slightly older models, like the Canon EOS RP.

What's the best overall full-frame camera you can buy right now? Our current top pick is the Nikon Z6, a mirrorless model that combines excellent performance and plenty of features in a light body that handles well. It’s also pretty stellar for video and the price is relatively affordable.

That said, new models like the Canon EOS R5 and Canon EOS R6 are en route to shake things up, and there might well be another model that's better suited to your budget and shooting needs. So read on to find out the best full-frame cameras you can buy right now, whatever your experience or expectations.

Best full-frame cameras in 2020:

Nikon Z6

Nikon's Z6 was the first of two cameras in Nikon's Z system, and while it's no longer the newest model around, it retains its spot at the top of our best full-frame camera list. It's our pick thanks to a brilliant blend of features, performance, handling and price: the 24.5MP sensor delivers beautiful results with great color reproduction and fine detail, while the 273-point AF system works very well and has excellent frame coverage. There's also an impressive 12fps burst shooting mode, sensibly laid-out controls, and a large, bright electronic viewfinder. Existing Nikon user? The FTZ adapter means you'll be able to use your existing F mount lenses too (though check compatibility for older lenses). All this makes the Z6 a brilliant choice for the enthusiast photographer or pro photographer looking for a second body. We can't wait to see where this system goes from here.

Sony A7 III

The A7 III has become a firm favourite among enthusiasts and pros these last couple of years, and for good reason. In contrast to the more niche A7R IV and A7S II, the A7 III is a camera for everyone, whether they shoot stills or videos, action or static subjects, indoors or out. The sensor has a modest 24MP but its backlit design makes for better light gathering, while the advantage of sensor-based stabilization means you don't need to worry about this being in your lenses, which is something many other mirrorless cameras don't have as standard. Add to that a 710-shot battery life – impressive for a mirrorless camera – a slew of video-specific features and the EyeAF feature for tack-sharp portraits and you have yourself quite some camera.

The A7R IV is the studio-friendly camera in Sony’s full-frame line-up, albeit one that's just as at home shooting action or landscapes. It has an extremely high resolution 61-megapixel sensor, up from 42.4 megapixels in the last version. Such a high pixel count lets the camera retrieve incredible amounts of detail when mounted to a sturdy tripod, in controlled lighting. Noise predictably creeps in more quickly than in a lower-resolution full-frame model, but this is an excellent all-round camera. And while it demands careful shooting for the best results, effective stabilization means it still works well handheld. 4K video quality is great too, aside from some rolling shutter effect.

Nikon D780

Don’t believe the naysayers: the DSLR isn’t dead and the Nikon D780 proves it. One of the best full-frame cameras you can buy, it delivers a fantastic shooting experience that should appeal to fans of DSLR handling, while also offering many modern features familiar to mirrorless users. Its sturdy, water-resistant magnesium alloy body might be big and heavy, but the trade-off is a satisfyingly chunky grip. Image quality from the D780’s full-from 24.5MP sensor is truly fantastic, too, aided by Nikon’s EXPEED 6 image processor. Exposures are nicely balanced, courtesy of a metering and scene recognition system borrowed from the D850, while the 273-point on-chip phase detection system – as used by the mirrorless Z6 – ensures fast and reliable autofocus performance when using Live View on the tilting touchscreen. The lack of in-body image stabilization is a shame, but superlative battery life rounds out what is a superb – if pricey – full-frame all-rounder.

Nikon Z7

Nikon's first full-frame mirrorless camera along with the Z6, the Z7 is triumph. As a first-generation camera we should expect the odd hiccup, but the Z7 has been crafted with consideration and it behaves far better than we would expect. A solid sensor, combined with effective image stabilization, together with a beautiful EVF, excellent handling, competent AF performance and great response throughout form the bones of what make this camera such a pleasure to use. The fact that Nikon allows you to use F-mount lenses through the FTZ adapter also makes the journey from DSLR to mirrorless relatively painless if you've already built up a collection of lenses. Like what you see but cash is tight? The 24MP Nikon Z6 (position 1) deserves your attention.

Nikon D850

The D850 may have had some of its thunder stolen by the similar Z7 (position 3) but it retains a lot of appeal. It's one of the most advanced DSLRs we've ever tested, with the winning combination of a 45MP full-frame sensor and 7fps burst shooting at its heart, and a wonderful 153-point AF system that makes light work of keeping up with moving subjects. Videos are recorded in 4K quality and are top notch, while build and design are as close to perfect as it gets right now. Its weight and size make the Z7 a little more desirable for most users, but if you're shooting sports or other moving subjects and plan on getting the most out of that focusing system, it's a cracking option.

Canon EOS RP

Canon's first full-frame mirrorless camera, the EOS R, delighted in some ways and frustrated in others, but the EOS RP made a much more positive impression. While technically a more junior model and not as fully featured, its much smaller and lighter body, together with a far nicer price, means that it's far more accessible for those who were hoping to make the jump to mirrorless but didn't want to stretch all the way to the EOS R. Without only around 4MP difference between the two you're not really sacrificing much in terms of sensor resolution, while the responsive touchscreen, fast autofocus and deep buffer makes it a pleasure to use in all kinds of situations. Let's hope Canon fills out the lens range with some smaller and more affordable options, as most current options aren't quite the most suitable partners.

Panasonic S1R

The S1R offers some very impressive tech in a supremely rugged body. The 5.7million-dot viewfinder is, without question, the most impressive on the market right now, while stellar video quality, great image stabilisation and a huge buffer all put a big smile on our face too. At the time of its release, the 47.3MP sensor had the highest number of pixels on any full-frame mirrorless camera too, although it's now been beaten by the Sony A7R IV. Its main party trick, however, is the ability to output 187MP images; quite how often you'll need to print your images to the size of a small country is another matter, but this clearly gives you massive scope for extreme cropping, enlargements to all sizes and homing in on the smaller details in the scene. We have some reservations with the autofocus system, and it's a little on the beefy side too, but for its combination of build, features and overall execution, the S1R scores many points.

Canon EOS 5D Mark IV

The EOS 5D Mark IV pretty much tweaks and improves everything the Mark III offered. This includes a brilliant 30.4MP sensor that delivers pin-sharp results, together with an advanced and sophisticated 61-point AF system, a pro-spec performance, 4K video and some very polished handling. We have a few reservations, such as the crop factor and inefficient Motion JPEG option when shooting 4K videos, while the 30MP sensor resolution and 7fps burst rate aren't as competitive at this price point as they used to be when the camera was first launched. Still, if you're a Canon user looking for the very best DSLR for a wide range of purposes, this is still very much it.

Sony Alpha A9 II

The main mirrorless rival to the incoming Canon 1DX Mark III and Nikon D6 for pro sports photographers, the Sony A9 II builds on the considerable foundation laid by its predecessor, adding dozens of improvements that collectively make it a one of the best cameras we've tested. The main improvements are its deeper grip and boosted 10fps burst shooting with the mechanical shutter. These are added to the refined 693-point AF system, which now offers even better subject tracking than the original Sony A9 and is perfect for sports and wildlife. It's not cheap, of course, but if you're an action fan, you won't find a better mirrorless camera than this.

Also consider…

Looking for something a bit cheaper? Here's a great value full-frame option:

When the original EOS 6D launched, it offered the best bang for your buck and that trend continues with the second generation DSLR – the EOS 6D Mark II still offers an an excellent entry into the full-frame market. Released in 2017, it has a significant bump in features over it's predecessor, including a higher sensor resolution at 26.2MP, a better autofocus system with 45 cross-type AF points, 6.5fps burst speed and introduces touchscreen functionality to the 6D line. Performance in the real world is smooth and you won't find much to complain about in terms of image quality. And you get all that for around $1,500 / £1,349 / AU$1,999, which is excellent value for money.
