The Buyers guide to...Best professional mirrorless cameras

Read our Nikon Z9 Review

While the 45.7Mp Nikon Z7 II has a lot in common with the excellent Nikon Z7 and uses much of the same technology (including the same sensor), the mark II camera has a second memory card slot which means it addresses the main concern that photographers had about the original camera. One slot accepts XQD or CFexpress cards while the other is for SD-type cards and is UHS-II compliant

Nikon also doubled the Z7 II’s processing power in comparison with the Z7 II by giving it two Expeed 6 processing engines. This enabled a boost in the continuous shooting rate from 9fps to 10fps and enables 4K shooting at 60P.

That extra processing power also enables Eye-detection AF for humans and animals in video mode as well as stills, and enhances the low-light capability of the autofocus system.

The Nikon Z7 II has the same build and handling as the Z7, Z6 and Z6 II, and it’s the best interface available in a Nikon camera to date.

While Canon says that the EOS R3 sits below the Canon EOS-1D X Mark III in the company’s line-up, there can be little doubt that the new 24.1MP full-frame mirrorless camera will attract the attention of many of the flagship DSLR’s users. It’s aimed at the same pro sports and news photographer audience and has a fabulous feature set to keep them happy.

Canon used a full-frame backside-illuminated stacked CMOS sensor inside the Canon EOS R3 and paired it with the Digic X processing engine to deliver quick data readout and minimise rolling shutter. It offers an excellent blend of resolution, noise control and file size with blistering AF performance.

What’s more, the R3 can shoot raw or Jpeg files at up to 30fps with full exposure metering and autofocus (AF) tracking when the electronic shutter is selected. It’s a great choice of camera for sport, action and news photography.

The R5 and R6 were significant introductions for Canon when they launched in 2020. They gave significant depth to the EOS R system. But the addition of the EOS R3 takes things up a notch with its ability to shoot at 30fps, Eye Control AF and a high-resolution vari-angle touchscreen. It’s also the first double-gripped mirrorless camera, and while Canon says that it sits below the EOS-1D X Mark III, the R3 looks set to poach a few flagship DSLR sales and convert more professional photographers to mirrorless technology.

Canon has shown us a vision of the future for mirrorless cameras and while the R3 is beyond the budget of many photographers, the AI that it employs will trickle down to more affordable cameras.

Although its position was technically usurped by the Canon EOS R3, the Canon EOS R5 is Canon’s flagship mirrorless camera and it was the most exciting camera announced in 2020.

Its 8K video capability stole most of the headlines when it was revealed, but the Canon R5 is at heart a 45Mp stills camera with an incredible autofocus system. This Dual Pixel CMOS AF II system has 5,940 selectable AF points and superb eye detection AF for humans, animals and birds that works in both video and stills mode.

Like the Canon EOS R6 announced at the same time, the EOS R5 has 5-axis in-body image stabilisation. In the R5 it enables shutter speed compensation of up to 8EV.

Canon pitches the R5 at around the same level as the Canon EOS 5D Mark IV, which means it’s designed for use by experienced enthusiast and professional photographers. It combines a healthy collection of button and dial controls with an excellent touch-control interface on the 3.15-inch 2.1-million dot vari-angle screen.

While 8K video is of limited appeal, the R5 is capable of producing superb results with the 4K HQ (High Quality) mode especially impressing. The still image quality is also excellent all the way up to around ISO 25,600.

The Alpha A1 is Sony’s most advanced camera to date, it combines a high-resolution full-frame sensor with high-speed performance. It features a new 50.1Mp full-frame stacked Exmor RS image sensor and can perform up to 120 AF/AE calculations per second.

Thanks to its impressive processing power, the Sony A1 can shoot at up to 30fps (frames per second) while its large buffer allows for sequences of up to 155 full-frame compressed RAW images or 165 full-frame JPEGs to be shot at that rate.

In addition to improved Real-time Eye AF for humans and animals, the Alpha 1 uses high-level subject recognition technology for Real-time Eye AF for birds. Algorithms also maintain the AF tracking if a sitting bird takes off or the framing changes.

The Sony A1 is the first Sony Alpha series camera to feature 8K 30p 10-bit 4:2:0 XAVC HS video recording. It’s also capable of shooting 4K 120p / 60p 10-bit 4:2:2 video and offers S-Cinetone colour. It uses 8.6K oversampling for enhanced resolution and, naturally, the 8K footage can be used for 4K editing during post-production.

The Sony A 1 has a 9.44 million dot OLED Quad-XGA electronic viewfinder, with a refresh rate of up to 240 fps, ensuring no blackout, delivering the highest resolution in its class. In addition, there’s a 3-inch 1,440,000-dot tilting touchscreen that features the revised menu arrangement and more extensive touch-control that was first seen in the Sony A7S III.

In case a resolution of 50Mp isn’t enough, the Sony A1 has Sony’s Pixel Shift Multi Shooting mode onboard to enables 16 full-resolution images to be composited.

You can order the Sony A1 from Wex Photo Video and Park Cameras in the UK and Adorama or B&H Photo Video in the USA. You can also find the latest Sony A1 offers at Amazon UK and Amazon US.

The Sony A7R Mark IV’s 61-million-pixel 35mm sensor is a world first, which the company says delivers ‘medium format quality’.

The sensor is back-side illuminated, and it provides 15 stops of dynamic range. As well as 61-megapixel images, the Sony A7R Mark IV can also produce images with 26 million pixels in APS-C crop mode.

What’s more, its revampled Pixel Shift Multi-Shooting mode can produce images at 240-megapixel resolution. It does this by capturing 960 megapixels worth of data from 16 images, which it then composites together using Sony’s Imaging Edge software.

The A7R Mark IV boasts 567 phase-detection AF points in full-frame mode, which cover 74% of the frame. In the camera’s APS-C mode it has 325 AF points which then cover nearly the entire frame. There’s also Sony’s excellent AI-driven Real-time Eye AF (for humans and animals ins stills mode) and Real-time Tracking modes, which is invaluable for portrait, wedding, sport, pet and social photography.

Depsite its high resolution, the Sony A7R IV is also built for speed and can capture full-resolution 61-megapixel images in continuous shooting mode at up to 10fps, and up to 68 images per continuous burst.

Also among its key features is 5.5-stop, 5-axis in-body image stabilisation, wireless tethering capability, faster USB connection, 802.11ac Wi-Fi plus Bluetooth and studio lighting support.

It all adds up to make the Sony A7R IV one of the best cameras available right now.

While the X-H1 was seen as Fujifilm’s most video-centric camera, the Fujifilm X-H2S is the speed king. Its new 26.1MP X-Trans CMOS 5 HS sensor comes in a newly stacked design and is

paired with the 5th generation X Processor (X-Processor 5), which has twice the speed of the previous engine. Together the sensor and X-Processor 5 enable some impressive headline figures including a maximum continuous shooting rate of 40 frames per second (fps) at full-resolution with full autofocus (AF) capability, 6.2K video at 30p, 4K video at 120p, 120fps Live View and enhanced rolling shutter control with the full sensor being cleared in 1/151sec for stills and 1/180 sec when shooting video.

The new sensor has pixels that measure 3.76um, plus a phase detection system that uses 2.16 million pixels. Also, more data points are used to calculate the focus at 40fps that with the X-T4 at 20fps.

There are some handling changes in comparison with the X-H1, some of which might be less welcome than others, but anyone looking at this camera with fresh eyes cannot fail to be impressed by its build and capability.

The Fujifilm GFX100S is a medium format camera that doesn’t feel like a medium format camera. With the right lens, it can blend in with full-frame DSLR and mirrorless camera yet it has a sensor that’s 1.7x the size.

It has the same 102Mp back-illuminated CMOS sensor as the Fujifilm GFX100, which means it can produce images that measure 98.62 x 73.96cm or 38.8 x 29.1-inch when printed at 300ppi. And there’s Fujifilm’s Pixel Shift Multi Shot mode that enables it to produce 400Mp images with a little help from a computer running Fujifilm’s Pixel Shift Combiner software.

If you look at images shot at the top native sensitivity setting of ISO 12,800 at 100% on screen, you’ll see a fair amount of luminance noise in the raw files, but as you zoom out, it disappears and there’s a long way to zoom out! Of course it depends what you want to do with your images, the the Fujifilm GFX100S is one of the few cameras that we’d feel reasonably happy about using the upper sensitivity expansions settings.

While the GFX100S’s AF system is a bit fidgety, it’s responsive and can get moving subjects sharp. The Eye AF isn’t the best around, but it’s useful for portraits and the level of detail captured in low to mid-range ISO images is fantastic.

Read our Panasonic Lumix GH6 Review

In early 2020 Panasonic announced that via a strategic partnership with Atoms it had developed new firmware for the Lumix S1H that enables the camera to output a maximum 5.9K/29.97p RAW video data to the Atomos Ninja V.

Shortly after this announcement, the Panasonic S1H became the first ‘Netflix-approved’ camera on the market.

The S1H is aimed at serious filmmakers, but its price tag is under the the £4,000 threshold, and it packs some serious firepower.

Panasonic’s flagship full-frame mirrorless camera offers 6K video recording and 10-bit 60p 4K/C4K, aided by a 35.6 x 23.8mm, 24.2-megapixel full-frame CMOS sensor. It can record 6K at 24p at a 3:2 aspect ratio, 5.9K at 30p in 16:9, as well as 10-bit 4K/Cinema 4K footage at 60p using the Super 35mm image area.

As if that isn’t enough, it can record 4:2:2 10-bit 4K footage at 30p over the full image area.

The Panasonic S1H also delivers 14 stops of dynamic range – the same as Panasonic’s cinema cameras – along with a slew of other video specifications aimed at professionals such as Panasonic’s V-Log/V-Gamut log modes, HDR in HLG (Hybrid Log Gamma), 4:2:2 10-bit HDMI output and Anamorphic 4:3 modes.

The OM-D E-M1X is a doubled-gripped mirrorless camera. It uses Olympus’s Pro Capture mode for shooting stills of very fast action. Thanks to the dual processors, there’s also no blackout in the viewfinder when this is in action.

In Pro Capture High mode, the shooting rate is 60fps, but the focusing is fixed at the start of the sequence. Switch to Pro Capture Low, and you can shoot at 18fps with continuous focusing.

Pro Capture mode is designed to help you record fleeting moments that are easily missed. To that end, when it’s activated the camera starts writing images to the buffer as soon as the shutter release is half-pressed. Once the shutter button is pressed fully, the 35 images that were buffered immediately before it was pressed are recorded along with 100 from immediately after.

There’s also a standard sequential shooting mode that uses the mechanical shutter. When this is in action, the maximum shooting rate in single AF mode is 15fps for 143 raw files. In continuous autofocus mode, the maximum is 10fps for 283 raw files.

A High Res Shot mode also delivers larger and more detailed images. The 50Mp Handheld mode captures the images quickly but then takes a little longer to render the final shot than the Tripod mode. Comparing the results with standard images reveals a nice jump in the level of detail.

Similarly, the 80Mp tripod mode delivers impressive results. It gives a significant boost to the size of print that you can make. That compositing also has a beneficial effect on the dynamic range as there’s more detail visible (and extractable) from the shadows.

OM System has delivered the camera that many Olympus users have been hoping for, a camera that offers everything the Olympus OM-D E-M1X has (and more) in the more compact, single-gripped form of the Olympus OM-D E-M1 Mark III. Look beyond the resolution and you’ll see a new sensor paired with a processing engine that’s 3x faster than its predecessor, plus enhanced autofocusing, AI-enabled subject detection and full-resolution continuous shooting at up to 120fps or 50fps with continuous focusing. There’s also a refreshed menu, faster high-resolution shooting and an even more robust body. It adds up to make a great camera for wildlife, travel and general photography.
