2018 has already welcomed a barrage of new cameras equipped with 4K video recording, and now almost every major camera manufacturer has implemented 4K shooting somewhere in their lines.
Perhaps most impressively, the technology has been successfully stretched over models of all billings. So, whether you’ve only got a few hundred pounds to spend or you're willing to stretch to a handsome four-figure sum, it’s likely you can afford a camera with the technology on board.
Just because two cameras have 4K recording, however, doesn't mean to say they're equal. The use of different sensors and different methods of capture, together with variations in output possibilities, mean two 4K cameras can behave quite differently.
Even something as simple as whether the camera uses the full width of the sensor or applies a crop factor is vital to consider, as this has a significant effect on your effective angle of view. And all of the above is before we even consider supporting features such as headphone sockets, focus peaking, zebra patterning and Log profiles.
To make things simple, we’ve rounded up what we think are the fittest 4K cameras on the market right now, and sum up why they've made the cut.
Best 4K cameras 2018
1. Panasonic Lumix GH5S
This is one uncompromising video tool
Type: Mirrorless | Sensor size: Micro Four Thirds | Resolution: 10.2MP | Lens: Micro Four Thirds | Viewfinder: EVF | Monitor: 3.2-inch vari-angle display, 1,620,000 dots | Maximum continuous shooting speed: 12fps | Movies: 4K | User level: Expert
While it can shoot stills quite happily (although at a pretty limited 10.2MP resolution), this should be seen first and foremost as a video camera – if you want to do both you've got the Lumix GH5 (below) to fill that brief. While the absence of built-in image stabilization might be a disappointment for some, that issue aside the breadth of video features is incredibly impressive. If you want to shoot professional-quality footage without remortgaging your house to buy a pro video camera, you won't find a better video-focused camera right now.

2. Panasonic Lumix GH5
The Lumix GH5 is a feature-laden 4K workhorse
Type: Mirrorless | Sensor size: Micro Four Thirds | Resolution: 20.3MP | Lens: Micro Four Thirds | Viewfinder: EVF | Monitor: 3.2-inch vari-angle display, 1,620,000 dots | Maximum continuous shooting speed: 12fps | Movies: 4K | User level: Expert
Until the arrival of the Lumix GH5S, the GH5 was the pick of the bunch for those looking to shoot video. Quite a bit cheaper than the newer GH5S, the GH5 is a bit more versatile for those wanting to shoot both stills and video, and the video specification is still very impressive, allowing you to shoot Cinema 4K (4096 x 2160) at 60p with a bit rate of 150Mbps, while Full HD video can be captured up to 180fps. That's not all, as the GH5 offers color subsampling at 4:2:2 and a color depth of 10-bit, delivering greater color information and richer graduations. The GH5 also offers live output to external recorders such as Apple ProRes via HDMI, as well as simultaneous internal recording.

3. Sony Alpha A7S II
Excellent footage, huge dynamic range and a compact size – what’s not to like?
Type: Mirrorless | Sensor size: Full-frame CMOS | Resolution: 12.2MP | Lens: Sony E mount | Monitor: 3.0-inch tilting display, 1,228,800 dots | Viewfinder: EVF | Maximum continuous shooting speed: 5fps | Movies: 4K | User level: Expert
At the time of the A7S II's review we said it was the best video-shooting stills camera available, and while much has changed in the market we still reckon it’s a compelling option for the videographer. One of its major selling points at launch – internal recording of 4K footage – has since been matched by many others, but it’s the modest pixel count of its sensor that splits it from its rivals. We found its dynamic range to be very high, and consistently better than rivals at higher sensitivities, while noise was also shown to be lower than cameras with more populated chips. It also has the advantage of using the whole sensor width for recording video, and of being able to record to the memory card while outputting 4:2:2 footage to a HDMI recorder, but proves itself to be capable for stills shooting too. Autofocus is generally fast and built-in image stabilisation is a huge bonus, while the body is sturdier than its predecessor’s too. Overall, while it may not be the newest model, its sensor and video specs give it a handful of advantages over its rivals.

4. Sony Alpha A6500
Sony’s 4K-enabled APS-C model is a smasher
Type: Mirrorless | Sensor size: APS-C | Resolution: 24.2MP | Lens: Sony E mount | Monitor: 3-inch tilting touchscreen, 921k dots | Viewfinder: EVF | Maximum continuous shooting speed: 11fps | Movies: 4K | User level: Intermediate
The previous APS-C-based Alpha A6300 was a big hit with enthusiast users, and the Alpha A6500 builds on its success in many ways. The camera records 6K footage that’s downsampled to 4K for the benefit of quality, and uses the efficient XAVC S codec that has a rate of 100Mbps. This is joined by Log gamma modes, 120fps HD recording (also at 100Mbps) and enhanced zebra patterning to keep an eye on exposure. You also benefit from a 425-phase-detect-point focusing system for rapid focus and a 2.36-million-dot OLED viewfinder, together with 11fps burst shooting at full resolution, all inside a dust- and moisture-resistant body. That's not to mention the welcome addition of Sony's 5-axis in-body image stabilization system. Now that the price has started to fall it would also be a fine choice as an upgrade over previous APS-C-based Sony models.

5. Nikon D850
High resolution meets high speed
Type: DSLR | Sensor size: Full-frame CMOS | Resolution: 45.4MP | Lens: Nikon F | Screen type: 3.2-inch tilt-angle touchscreen, 2,359,000 dots | Viewfinder: Optical | Maximum continuous shooting speed: 7fps | Movies: 4K | User level: Expert
The long-awaited successor to the D810 arrived earlier this year, and Nikon certainly didn't hold back with the specs. With a fresh 45.4MP full-frame sensor, a highly advanced 153-point AF system and 7fps shooting, supported by features such as a tilting touchscreen and whole suite of connectivity options, the the D850 is the most advanced DSLR we've seen. Video-wise, there’s lots to love. The camera is capable of 4K UHD capture at 30p/25p/24p, and that's using all the sensor - no unwanted cropping here, allowing you to take full advantage of your lenses. Other video features include ports for both microphone and headphone sockets, as well as a Flat Picture Profile, zebra patterning and Power Aperture Control. You can also record at 120fps in Full HD quality. A brilliant DSLR that's great at shooting video too.

6. Olympus OM-D E-M1 Mark II
Top-end OM-D model impresses across stills and video alike
Type: Mirrorless | Sensor size: Micro Four Thirds | Resolution: 20.4MP | Lens: Micro Four Thirds | Monitor: 3.0-inch free-angle display, 1,037,000 dots | Viewfinder: EVF | Maximum continuous shooting speed: 60fps | Movies: 4K | User level: Expert
“The best Micro Four Thirds camera yet” was what we concluded from our time testing the Olympus OM-D E-M1 Mark II, and video is one area where Olympus has made significant improvements over previous models. Not only do you get 4K capture in both DCI and UHD flavours, you also get clean output over HDMI at 4:2:2, a headphone port for audio monitoring and the benefits of Olympus’s fast Hybrid AF system, which works in conjunction with the touchscreen for even easier subject selection. Whether you’re shooting stills or videos, you also get one of the most effective image stabilisation systems we’ve yet seen, which will please those who expect to be largely using the camera handheld. Other reasons why the camera walked away with a full five stars include its excellent weather-sealing, lifelike EVF, and the capability to fire at 18fps with continuous AF and AE tracking. Those who want to easily achieve a very shallow depth of field may not prefer the smaller Micro Four Thirds sensor over larger-sensor offerings, but with the right lens and technique you can still isolate subjects from their surroundings on such a camera without bother. In any case, while Panasonic may have had a head start with video, the OM-D E-M1 Mark II certainly sets the bar high for a flagship Micro Four Thirds camera.

7. Fujifilm X-T3
Fujifilm ramps up the video specs from the already capable X-T2
Type: Mirrorless | Sensor size: APS-C | Resolution: 26.1MP | Lens: Fuji X | Monitor: 3.0-inch tilt-angle display, 1,040,000 dots | Viewfinder: EVF | Maximum continuous shooting speed: 11fps | Movies: 4K | User level: Intermediate/Expert
Fujifilm made a lot of effort to revamp many aspects of the X-T2’s spec sheet to craft the X-T3, and improvements in video recording were more significant than is usually the case for such a model. The key changes include the option to capture 10-bit video at 4:2:0 internally, together with a far denser phase-detect AF array that makes for more refined subject tracking. There’s also a forthcoming Hybrid Log Gamma option, on top of the F-Log setting that can be used for internally captured footage provided as standard. The camera also has the bonus of applying no crop when shooting 4K footage at 30p, and only a minor 1.18x crop when boosted to 60p shooting, in either DCI 4K or UHD 4K modes, while both mic and headphone sockets are also now both incorporated into the body too. In our review we found the camera to deliver detailed and natural footage, whether you’re capturing conventionally or using one of the slow-motion options, and this is on top of a stellar performance elsewhere, with great autofocus, lovely image quality from the new sensor and speedy response throughout operation. Another smasher from Fujifilm.

8. Nikon Z7
Strong video specs matched by equally impressive performance makes the Z7 shine
Type: Mirrorless | Sensor size: Full frame | Resolution: 45.7MP | Lens: Nikon Z | Monitor: 3.2-inch display, 2,100,000 dots | Viewfinder: EVF | Maximum continuous shooting speed: 9fps | Movies: 4K | User level: Expert
Nikon’s joint first full-frame mirrorless camera is its most serious assault on the video market to date. While the D850 remains an excellent choice for DSLR users looking to capture video alongside their images, the Z7 has a handful of significant advantages for the videographer. Perhaps most crucially, the presence of both sensor-based and electronic VR mean that the camera does great job to keep things stable, whatever the lens you're using, while 435 sensor-based phase-detect AF points that are available during video recording do very well to keep everything focused and transitions nice and smooth. The 10bit N-Log shooting option, which is also absent from the D850, gives you a better starting point for grading footage, and it's great to see 4K footage being recorded using the full width of the sensor too. We’d like to have seen a 4K60p option, and a little rolling shutter remains, but we were otherwise very impressed by the way Nikon has launched it's new system.

9. Sony Cyber-shot RX10 IV
A cracking travel camera with excellent video – but it comes at a price
Type: Compact | Sensor size: 1-inch CMOS | Resolution: 20.2MP | Lens: 24-600mm, f/2.4-4 | Monitor: 3-inch tilting touchscreen, 1.44 million dots | Viewfinder: EVF | Maximum continuous shooting speed: 24fps | Movies: 4K | User level: Intermediate/Expert
If you're looking for a powerful all-in-one camera, then you're not going to go far wrong with Sony's brilliant RX10 IV. With a long and fast 24-600mm f/2.4-4 zoom lens partnered with a stacked 1-inch type 20.2MP sensor and fast 315-point phase-detect AF system, it's an incredibly versatile camera. It doesn't disappoint when it comes to video either, with 4K UHD footage captured with 1.7x more information than actually required without any pixel binning, before being downsampled to 4K for the sake of quality. This happens at a 100Mbps maximum bit rate, and you can boost the camera up to 960fps for slow-motion footage too. All of this is supported by a clean HDMI output, zebra patterning and both microphone and headphone ports. You also get an S-Log2 gamma profile in addition to the Picture Profiles (which you can adjust), and Sony’s Gamma Display Assist mode to help you get a better idea of what graded footage would look like. It’s not cheap, but there's nothing quite like it.

10. Sony Cyber-shot RX100 VI
You won’t get much change from four figures, but there’s no doubting its capabilities
Type: Compact | Sensor size: 1-inch CMOS | Resolution: 20.1MP | Lens: 24-200mm f/2.8-4.5 | Monitor: 3-inch tilt-angle touchscreen, 921k dots | Viewfinder: EVF | Maximum continuous shooting speed: 24fps | Movies: 4K | User level: Intermediate
Sony has enjoyed much success with its RX100 line, and its latest RX100 VI picks up from where the Mark V left off. Footage is recorded at 1.7x the amount required and subsequently downsampled to 4K. You can record at up to 30fps and take advantage of the stepless control ring around the lens, while supporting functions include an S-Log2 gamma profile, focus peaking, zebra patterning and slow-motion recording. Naturally on such a small camera you don't get ports for microphones or headphones. Still, you do get Sony’s excellent hybrid AF system for focusing. Add a high-quality EVF, a versatile 24-200mm zoom lens, a tilting touchscreen and a super-fast 24fps burst-shooting mode, and it’s amazing that something so powerful can still slip inside your pocket. The price tag is significant, but if it’s beyond your budget there's still the RX100 IV, which manages to offer 4K shooting and plenty of shared technology at a keener price point.
