Resolution-wise, the α7R IV sits at the top of Sony’s ‘full frame’ camera range, replacing the 42.2-megapixel α7R III , which continues to be available. Stills photographers looking for the extra resolution will doubtless welcome the upgrade.

The A7R IV proves that Sony is still very much on a roll with its Alpha line. While a handful of niggles from previous models remain, the class-leading pixel count, revamped Pixel Shift Multi Shooting mode and autofocusing improvements in particular show the company continuing to innovate, and push...

Great handling with improved ergonomics; Very fast and intelligent AF system; Bright; sharp and high-contrast viewfinder; Excellent 4K video quality; Pixel Shift Multi Shot capable of superb detail; Well-behaved metering system

Some AWB and focus issues; Rolling shutter noticeable in videos; Mode dial more awkward to access than before; Touchscreen could be better; No in-camera raw processing; No motion correction in Pixel Shift mode

It says something that the a7R IV, which brings with it an easily handheld form factor, a vast lens selection, and the ability to capture just about any subject, from scenice landscapes to professional sports, is downright competitive with medium format systems in terms of pixel count.

60.2MP full-frame imaging; 10fps Raw capture; Real-Time Tracking autofocus; 5-axis image stabilization; Big, crisp EVF; Tilting touch LCD; Dual UHS-II slots

Lower-pixel cameras are better for video; Phase detection doesn't extend to edge of frame; Big file sizes

The Sony a7R IV ($3,499.99, body only) is the follow-up to the popular a7R III. It takes the same concept—a full-frame mirrorless camera built for high-resolution capture—to the next level. Where the previous two entries in the series shared the same 42.4MP sensor, the a7R IV shoots at 60.2MP, a significant increase in resolution. It maintains its predecessors' 10fps burst rate, improves autofocus capabilities, and offers sundry updates all around, especially in ergonomics. After some time using it, we can confidently say it's the best high-resolution, full-frame camera on the market, and our Editors' Choice. A Tried-and-True Design The a7R IV doesn't stray too far from the template Sony has set for other recent models in the series, including the a7R III that came before it. It is sized in line with others in its class, measuring 3.8 by 5.1 by 3.1 inches (HWD) and 1.5 pounds. There is a $400 add-on vertical battery grip available if you prefer a bigger camera. The handgrip ha...

The full-frame mirrorless Sony a7R IV outshines its high-resolution competition with an outstanding autofocus system and a superlative image sensor, delivering class-leading performance.

I bought this camera 2 days before I have to do a commissioned shoot at the recent Singapore F1 Grand Prix as I wasn't confident of nailing the shots I needed with the gear I already owned.

The Sony a7R IV is among the most capable cameras we've tested. It makes a compelling case that the days of choosing between speed-oriented cameras and resolution-oriented cameras are coming to an end. It wouldn't be our top choice for sports and action purists (all those megapixels result in many megabytes of storage), but for those users that need this resolution on a regular basis and want to be able to photograph fast-moving subjects when necessary, the Sony a7R IV is the best option on the market right now.

Sony continue to innovate with the latest high-resolution, high-speed, BSI CMOS sensors, and this means they're able to offer high-resolution 61mp images, with low noise. The Sony E/FE mount has been around for a good length of time, and this means there's a good range of lenses available, and...

61mp full-frame sensor for high-resolution images, 5.76million dot electronic viewfinder, Built-in 5-axis image stabilisation, Good range of E/FE mount lenses, Multi-shot mode can produce even higher MP images

Screen is a little smaller than many, NTSC / PAL switchover, Auto white balance can be too cold, Menus could be improved

Let’s face it: you probably don’t need to take 61-megapixel photos, which makes the A7R IV a tough camera to recommend at its current asking price. That being said, it’s a fantastically powerful product that offers a surprising amount of speed and convenience for such a hi-res camera, and if it were more affordable we wouldn’t hesitate to award this impressive all-rounder a higher score. As it stands, cheaper models like the A7 III and A7R III make a lot more sense for the majority of buyers, so we’d definitely advise looking at those first.
