The Sony a7R IV is a highly-refined, feature-packed, extremely competent, well-constructed little camera that delivers sharp, incredibly-high-resolution images with impressive dynamic range. The upgrades in the version IV camera are signifcant with the new 61 MP imaging sensor being a highlight.

This is suppose to be an upgrade of an A7R4. Beside the higher LCD resolution, I think Sony do something to the firmware (A7R4A has its own firmware version) and make overall color a little bit more vibrant which I like a lot. Attached pics are with Tamron 28-75 G2

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

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...

Superb image quality, Fast continuous shooting, Superb autofocus system, Lightweight, compact and tough build

Overkill for vast majority of photographers, Byzantine menu system

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

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.

Landscape photographers, wedding and event shooters, studio photographers that specialize in portraits and product photography, and anyone that wants to make really big prints.

Dedicated sports and action shooters, those that must frequently switch from shooting stills to video and back again.

If you're looking for a full-frame camera that delivers images which compete against medium format cameras, while also offering the advantages of the most diverse lineup of full-frame lenses on the market and incredibly reliable autofocus, then the A7R IV is the camera to get.

Highest resolution of any full-frame sensor, Impressive overall image quality, Best autofocus in its class, Best feature set in its class, Compact & lightweight VS medium format, Lens selection VS medium format, Best ergonomics in its class/lineage

A7R III is already a very good, class-leading choice, May be less of a value compared to more affordable Sony's, Menus still complex & time-consuming, Buffer clearing still shuts down much of the camera, Ergonomics still have a few quirks

The Sony A7R Mark IV has several key improvements over its predecessor, including a bigger but more ergonomic camera body with a more comfortable grip; enhanced weather sealing; better button and control layout, including a locking exposure compensation dial; a faster, more accurate autofocus system...

Scorecard

- Some image noise issues when shooting at higher ISOs, - Antiquated and confusing menu system, - Rear LCD doesn't side-swivel, just tilts
