The best full-frame DSLRs have long been a staple among professional photographers - and for good reason. While mirrorless cameras now dominate the market, DSLRs remain a top choice for those who prioritize reliability, mechanical durability, and access to an extensive ecosystem of lenses and accessories.
Full-frame sensors offer key advantages over APS-C or "cropped" sensors. Their larger size enables them to capture more light and detail, making them particularly well-suited for low-light photography. They also provide a shallower depth of field when paired with longer focal length lenses, allowing for beautifully blurred backgrounds.
DSLRs are favored for their optical viewfinders and exceptional battery life, but choosing the right model can be daunting. After more than a decade using full-frame DSLRs from Nikon and Canon, I’ve developed a strong understanding of what works best for different photographers and budgets.
This guide isn’t just about ranking the latest or most high-tech models. Instead, I’ve carefully considered factors like performance, features, and price to help you find the best option for your needs. If you're looking for a more budget-friendly choice, our guide to the best DSLRs includes beginner and mid-range options. And if you're still deciding between DSLR and mirrorless, check out our in-depth DSLR vs. mirrorless comparison to make an informed choice.

The Quick List
With a 30.4MP sensor, Dual Pixel CMOS AF for live view and video and DCI 4K footage, the 5D Mark IV continues Canon's premium series of DSLRs admirably. It's one of my all-time favorites and a real workhorse if you're a professional.
The 6D Mark II has been discontinued but is still available at many retailers. Its vari-angle screen is great for creative composition, in a body that already handles well. It's ideal for existing Canon users wanting their first full-frame DSLR.
This 24.5MP advanced enthusiast model is heavy but well-made, a step up from the D750 but step under the D850. USB charging is a a modern touch, while the battery life is exceptional. I think it's the ideal upgrade to full frame for die-hard Nikon DSLR users.
The D6 is a beast of a camera for pros already invested in the Nikon system. With a 20.8MP sensor, it has faster autofocus and better processor than the flagship D5, making it perfect for wildlife and sports shooters. I found video a bit of a letdown, but that's not really what this epic DSLR is built for.
The D850 is another pro-grade DSLR, but its 45.7MP sensor is geared more towards high-resolution work (landscapes and portraits) than the sporty D6. With 4K video, 153-point AF points and a battery life of over 1,800 shots, I think it's one of the most complete DSLRs ever made.
The EOS-1D X Mark III is similar in form to the D6, with a 20MP sensor and huge grip. Stills are impeccable and the deep-learning autofocus is insane, but it's a filmmaker's dream too. You can record DCI 4K/60p video, or 5.5K RAW video using the full sensor width. The results are sensational.

Best all-rounder
Sample images
✅ You want a classic Canon: the Mark IV comes from a long line of pro DSLRs, and has inherited sensible controls and menus from its predecessors. It'll be familiar to most Canon users, even those upgrading.
✅ You shoot a bit of everything: this is a bit of a goldilocks camera, in that it's quite good everywhere but doesn't excel in one. If you shoot a range of subjects, it's well-specced for generalists.
❌ You want full 4K footage: the 5D Mark IV offers 4K video but at a big 1.64x crop. This is disappointing compared to modern mirrorless cameras at half the price.
❌ You're after an exciting design: DSLRs have shared similar designs for decades. If you're after smooth lines and a striking style, look to Fujifilm and Leica for that.
The Canon EOS 5D Mark IV is what you'd consider an old camera, having been released in September 2016. It isn't the highest-resolution DSLR in this guide or the one with the fastest autofocus system. It doesn't even have an articulating screen. But for the price point, it offers a blend of advanced specs for professionals, like a 30MP CMOS sensor and 4K video recording. Live view autofocus is also excellent, thanks to Canon's Dual Pixel CMOS AF system.
The Canon EOS 5D Mark III was one of my favorite all-rounder DSLRs ever, and the Mark IV builds on its successes. Its fully weather-sealed body is designed to withstand harsh shooting conditions – great for landscapes and travel work – and the 3.2-inch touchscreen lets you speed through Canon's menus and change most settings on the fly.
There’s Wi-Fi, NFC, and GPS for greater connectivity, particularly for sending images to the Canon app for sharing. The biggest problem for the EOS 5D Mark IV is the Nikon D850 (below), which is better in many respects, and almost the same price. The 5D Mark IV has the same 61-point AF system as the Canon EOS-1DX Mark II, but it lags behind the blistering subject acquisition speed that the 1DX Mark III can achieve.
The 5D Mark IV isn't the best 4K camera or DSLR, thanks to a heavy crop factor and the somewhat inefficient Motion JPEG format, but it still produces excellent quality video thanks to the cinematic DCI format (4096x2160 resolution) at 30/25/24fps internally, plus Full HD recording at 60fps. Image quality is undeniably fantastic when you pair the 5D Mark IV with Canon's L-Series lenses. If you shoot a bit of everything or want a full-frame DSLR with the best balance of price and specs, the 5D Mark IV is the ideal model.

Best entry-level full frame DSLR
Sample images
✅ You're on a budget: if you want an affordable full frame DSLR, the 6D Mark II is the lowest price point on this list. It's an even better proposition if you can find a second hand model.
✅ You're still learning: the camera is a great "beginner" full frame camera. It doesn't overwhelm you with tech you don't need, but you do get useful features like Wi-Fi, NFC and Bluetooth.
❌ You're a content creator: the Full HD video resolution on offer here is limited, and way behind what most mid-priced mirrorless cameras can now achieve.
❌You want the latest AF tech: the 6D Mark II has been superseded by the R6 and R6 Mark II mirrorless models. It's slower and less agile than both cameras by comparison.
The Canon EOS 6D Mark II has been discontinued officially, but as it's still on sale at several big retailers I've kept it on this list. For enthusiasts turning pro or hobbyists who want a small full frame DSLR, it offers some great specs.
As a hybrid full frame DSLR, it can capture 26.2MP stills, but Canon hasn't included the option of 4K video, probably to preserve some difference between the more expensive EOS 5D Mark IV. You get Full HD video at up to 60fps, but by modern standards, this is underwhelming, especially when mirrorless cameras like the Fujifilm X-S20 offer 6K for just over $1,000/£1,000.
Still, the 6D Mark II is capable of shooting well-balanced, dynamic images. Canon’s Dual Pixel CMOS AF sensor can deliver fast phase-detection autofocus in Live View mode, which is much smoother than the contrast autofocus system in previous iterations. Handling-wise, the fully articulated touchscreen looks great from any angle and works as a treat for selecting AF points on the fly, content creation at unique angles, and navigating the intuitive ‘Quick’ menu.
I always loved the 6-series DSLRs, given that the Canon EOS R6 was my first "proper" digital camera. If you're an enthusiast who isn't interested in shooting video, and you're looking for your next sensibly-priced full-frame DSLR, the 6D Mark II continues the lineage of great all-rounders.

Best full frame DSLR for enthusiasts
Sample images
✅ You can't afford the D850: the D780 sits below the more expensive D850, for photographers who don't need the mega-high resolution, but need an all-rounder.
✅ You've owned Nikon DSLRs before: if you prefer the way a DSLR handles or have a collection of F mount lenses already, the D780 is one of the best full frame DSLRs Nikon has made.
❌ You need a fast buffer: the two card slots allow you to shoot up to 68 Raw files or 100 JPEGs continuously. This isn't bad, but it's nowhere near the D6 or EOS-1D X Mark III.
❌ You want a vlogging screen: the D750's tilting screen is still useful for composing at low angles, but a fully articulating screen would have been better for video pieces to camera.
The Nikon D780 was one of the last DSLRs that Nikon released, but it remains one of the best enthusiast models. With uncropped 4K video, 12fps continuous shooting speed, and a host of small but valuable improvements like USB-C charging, the D780 is ideal if you want a full-frame sensor and access to Nikon's huge range of F-mount lenses (but don't want to pay a fortune).
Our reviewer felt that the D780 combines a long list of desirable qualities in a well-made, versatile and affordable camera. It doesn’t break any new ground anywhere. Still, the resolution is good enough, the continuous shooting is better than you’d expect, and the wide ISO range can cope with low light excellently.
The D780 handles well, too. It inherits the ergonomic design and handling of Nikon's classic DSLRs, featuring a comfortable grip, intuitive controls, and a tilting touchscreen LCD, making it user-friendly for photographers transitioning from other Nikon models or upgrading from entry-level DSLRs.
I always found the D780 a pleasure to use and handle, with a grip that's comfortable to use for long periods. Interestingly, the camera borrows a similar Live View AF system from the mirrorless Nikon Z6 and Z7, which means that live view previews are just as good on the LCD screen as through the optical viewfinder.
For videographers, the D780 offers flexible 4K UHD video recording at 30/25/24fps and Full HD at 120fps, and focus peaking and zebra stripes to enhance the overall experience and help you check your footage.
Having dual card slots adds versatility for photographers shooting images simultaneously or serves as an overflow for weddings and events. To my mind, the D780 delivers far beyond its price tag for stills and video shooters.

Best full frame DSLR for professionals
Sample images
✅ You shoot fast targets: autofocus is arguably the best of any Nikon DSLR, and the 14 fps continuous shooting speed means fewer missed opportunities.
✅ You need speedy transfers: with gigabit ethernet supporting 1000BASE-T, GPS and 5GHz Wi-Fi built-in, the D6 can send images to picture editors or libraries rapidly.
❌ You're not wedded to a DSLR: if you’re not already invested in the Nikon system or a DSLR, you might experience better performance from the Sony A9 II.
❌ You shoot video: the D6 is let down by poor video performance overall, both for resolution and live view focusing, which is erratic at best.
If you're a professional photographer, shooting mostly (or entirely) stills and you already own a lot of Nikon lenses, the D6 is a very good choice. This workhorse tank of a camera is built solidly, which means you can throw it around on outdoor shoots without worrying about causing damage. It'll last years, but it's certainly not portable (1,45kg with a battery and two CFexpress cards) or affordable.
With 105 cross-type autofocus points, the Nikon D6 is geared toward capturing fast action. Our reviewer found that the autofocus provided the sort of intelligent tracking and acquisition that you need in split-second moments. And when the view of a subject was interrupted, the D6 was still intelligent enough to keep up.
Eye AF is available in 3D tracking and Auto AF area modes, with an extra 17 customizable group area AF choices to make subject acquisition even more accurate. And if you need to send shots to clients rapidly, the D6 has built-in 5GHz Wi-Fi, GPS, and gigabit ethernet – that's pro connectivity that goes beyond the majority of models in this guide, except perhaps the mighty Canon EOS-1D X Mark III.
While the D6 offers 4K video resolution, our reviewer also felt that video focusing could be better. The fixed touchscreen offers little versatility for content creation or interesting angles, but then, the video element feels like an add-on here, as the D6 is still among the best professional cameras for pro sports shooters. That’s backed up by the 14fps continuous burst rate, and ISO Range up to 102,400 (Expandable to 3,280,000) for exceptional low-light performance in stadiums, racetracks, and anywhere else you’d want to challenge this epic DSLR.

Best full frame DSLR for resolution
Sample images
✅ You want high-resolution: if you're looking to make fine art and large format prints from your images, the D850's 45.7MP resolution and dynamic range is sure to impress.
✅ You want to angle the screen: unlike the EOS 5D Mark IV, the touchscreen is tiltable. This brings it in line with modern camera design and makes it easier to angle creative shots.
❌ You shoot pro video: there are better Nikon cameras for video. The Nikon Z 7 II matches the D850's resolution, but offers N-Log and HDR (HLG) movie output to give you more flexibility with your footage.
❌ You want speedy editing: with great resolution comes great file size. Images are around 50MB with lossless 14-bit compression, which could strain older PCs when editing.
The Nikon D850 made a real impact upon release, balancing both high-resolution imagery and speed and sensitivity in its specs list. I replaced my old Nikon D800 with the D850, and its 45.7MP sensor, 7fps burst shooting mode, and 153-point AF system made it an incredibly versatile combination, whether I was shooting wildlife, portraits, or fine-art work in high resolution. The buffer capacity of 51 uncompressed 14-bit Raw files is impressive, but only achievable with a multi-power battery pack. Either way, it makes the D850 a very capable sports DSLR, too.
The D850's battery is fantastic even by DSLR standards. I regularly got more than 1,800 shots out of a single charge, which is about three times the amount I now get from my advanced mirrorless camera. Although the D850 isn't as big or heavy as a sports camera like the Nikon D6 or Canon EOS-1D X III, it’s still a big camera – especially when fitted with a professional zoom lens. It has two fast card slots – one for XQD cards, and one for UHS-II SD cards – but XQD slots have never taken off in the same way as CFExpress, and can be expensive to get hold of.
Our reviewer felt that the contrast-based autofocus in live view mode stops the D850 from being one of the best 4K cameras for filmmaking. But its uncropped 4K video certainly makes it one of the best DSLRs for video. When you factor in its build quality and all the customization you need, you can see just how much the D850 appeals to a landscape photographer, wedding, or event shooter. It's a versatile and incredibly high-quality DSLR, it's just not built for traveling light.

Best full frame DSLR for video
Sample images
✅ You need a hybrid: it's possible to record RAW and MP4 video simultaneously to two separate memory cards, which is a revelation for pros who shoot both stills and video for clients.
✅ You want sharp eyes: eye and face detection on this camera is impeccable, and the deep-learning algorithms can track subjects even through googles or helmets.
❌ Stabilization is important: if you handhold a lot and need some extra leeway, stabilization can be important. Canon hasn't included IBIS on the EOS-1DX Mark III.
❌ You need the fastest Wi-Fi: if you're going to be transferring images via Wi-Fi, 2.4Ghz Wi-Fi is supported, but for 5Ghz Wi-Fi you need a separate module.
After Sony threw down a colossal gauntlet with the A9 II, many photographers wondered if there could be any serious competition, particularly in the world of DSLRs. The answer turned out to be a stonking "Yes", as Canon took the wraps off the incredible EOS-1DX Mark III. It combines the advantages of both DSLR and mirrorless technology to produce an amazing professional hybrid body.
The standout features that set it apart from other DSLRs in this guide is the deep learning autofocus, which essentially improves as you use it, plus a Smart Controller that makes using the camera an infinitely better experience. These mirrorless-style trappings come in a rugged body, but you also get an optical viewfinder and exceptional battery life.
The autofocus is affected by whether you use the optical viewfinder or Live View. Through the viewfinder, there are fewer AF points, lower resolution and you don’t get eye detection. In Live View, though, the Dual Pixel CMOS AF sensor and Digic X processor combine for subtle focus shifting and eye detection. The EOS-1DX Mark III uses the same tech as eye detection on the EOS R, and our reviewer found it to perform just as well.
Although designed for sports and heavy use, with epic weather-sealing throughout the EOS-1DX Mark III is also one of the best DSLRs for shooting high-end video. It has the best resolution of any DSLR in this guide, with uncropped 12-bit 4K 60p footage that extends to 5.5K RAW. In short? If you use this camera with one of the best DSLR gimbals you'll have an exceptional pro rig for a host of creative applications.

Best alternative full frame DSLR
Sample images
✅ You're an astrophotographer: using the camera's clever "Astrotracer" mode, you can capture sharp stars and celestial subjects without a motorised mount. It's ideal for night sky photos with less gear.
✅ You like direct controls: if you like quick-access to settings without having to dig through menus, the K-1 Mark II is adorned with buttons and controls, including a Smart Function dial on the top plate.
❌ You want a small camera: if you're after a compact companion, the K-1 Mark II isn't it. It's around the same weight as the Nikon D850 at just over a kilo.
❌ You're a hybrid shooter: video on the K-1 Mark II is an afterthought at best. Its limited to Full HD resolution, and you don't get faster phase-detect autofocus.
Pentax doesn't have the same brand awareness as Canon and Nikon, but the K-1 Mark II is still worth a look, particularly for outdoor shooters wanting a robust, solid, and dependable body, featuring a full set of weather seals. The megapixel count is impressive at 36.4MP, and the tilting rear LCD is similarly high-res, although I was sad to discover it wasn't a touchscreen.
The Pentax has a 5-axis sensor-shift image stabilization system that works for stills instead of just for movie capture. There are advanced modes for anti-aliasing correction, and for enhancing the capture of fine detail. For astrophotography, the unique ‘astrotracer’ mode employs the built-in GPS module, electronic compass, tilt sensors, and the stabilization system, to stop heavenly bodies streaking across the sky during long exposures.
There are downsides, though. The sensor-based autofocus for live view and movie capture is poor, and the movie resolution of 1080p feels ancient, as does the full-frame burst rate of 4.4fps. There's a reasonable range of full frame Pentax lenses to choose from, but you just don't get the same range as with Canon and Nikon.
The K-1 Mark II is a heavyweight, too, weighing over a kilogram before you fit a pro-grade lens like the HD Pentax-D FA 24-70mm f/2.8 ED SDM WR. That said, our reviewer noted how the size of the camera provides you with a good, solid grip, and has space for direct hands-on controls. Many traditionalists enjoy having settings buttons at their fingerprints, and the K-1 Mark II has them in spades.
If you’re shooting at night, it even has small LED lamps to illuminate the lens mount, screen and memory card slots. This DSLR is unique among the dwindling number of DSLRs on the market. It’s not shiny, and it’s not that fast, but it’s practical and dependable for your outdoor photography adventures.

How to choose the best full frame DSLR
Choosing the best full-frame DSLR means taking a close look at your needs, budget, and shooting style. Full-frame cameras typically come with a higher price tag compared to crop-sensor models, so if you're working with a limited budget, start by exploring the entry-level options in this guide.
One of the key factors to consider is resolution—the number of megapixels. A high-resolution sensor is great if you plan to make large prints or need the flexibility to crop your images without losing detail. However, keep in mind that higher megapixel counts mean larger file sizes, which will take up more space on your memory cards and slow down your editing workflow.
The camera's autofocus system is another critical feature, especially for tracking subjects in motion. While phase-detection AF systems have traditionally been better for action, sports, or wildlife, contrast-detection AF works well for stationary subjects like landscapes. That said, many brands now integrate advanced autofocus technologies. For instance, Canon’s Dual Pixel CMOS AF is designed to enhance autofocus speed and accuracy for both stills and video—but you’ll typically find it in higher-end full-frame DSLRs.
When it comes to brands, Canon and Nikon dominate the DSLR market, with Pentax holding a smaller niche. Both Canon and Nikon offer expansive ecosystems of lenses and accessories, so if you’re already invested in one brand, it’s often more cost-effective and practical to stick with it as you upgrade.
While comparing specs is essential, there’s no substitute for real-world insights. Be sure to check out our in-depth reviews to understand how these cameras perform in everyday use. With the right information, you’ll be able to make an informed decision and find the best full-frame DSLR to match your photography goals.
Is a full frame DSLR better?
Full-frame DSLRs offer better image quality than crop sensor cameras, especially in low light, and give you a shallower depth of field and background blur for creative applications like portraiture.
They also give you a wider field of view with landscapes and architectural photography. For pros or serious enthusiasts who want the best image quality and more creative control, full frame DSLRs are an excellent choice. However (as I've noted below) they also tend to be more expensive, heavier, and chunkier.
What is the disadvantage of full frame camera?
The obvious disadvantage of full frame cameras is that they cost more than crop sensor cameras, and that can put them out of the price range of many photographers. Full frame lenses come at a premium price, too, because of their higher build and image quality.
Full frame cameras are usually thought of as being heavy and bulky, which isn't what you want when travelling. They're generally bigger, to accommodate the larger sensor, while the extra weight comes from materials like magnesium alloy being used over plastic to make the camera more robust in adverse shooting conditions.
