The SonyA7R3 is the best mirrorless camers Perfect

The Sony A7R III is the epitome of competence, whatever your genre of photography. Only the more demanding sports and wildlife photographers will need the A9, while landscape and studio photographers will struggle to find a better full-frame camera.

Sharp images with plenty of detail and exceptional dynamic range; Much improved new battery with 650-single-shot-life; Lovely electronic viewfinder; Very respectable high-speed performance; Customisable 'My Menu' for direct access to most used controls

Still takes a while to work your way around the camera; LCD touchscreen lacks some functionality; Some buttons/dials are not the easiest to control; Still uncomfortable to hold with larger lenses

As a professional photographer for 40 years I depend on my equipment to perform, switching from a Nikon D850 to the A7RIII was a big move! After just 1 week I'm already impressed and racing ahead with the features.

I'm reviewing the a7R III from the perspective of a bird and wildlife shooter. I do lots of shooting of moving animals at predawn and after sunset, so dynamic range is a huge plus. Since I'm shooting feathers and fur, resolution is a high priority.

I opted for the a7Riii over the a7iii after evaluating both-mainly for the 42mp sensor. The grip could be bigger with more space for fingers. I also bought the battery grip which resolves that issue. I bought three Sony lenses at the same time and will comment on those as I gain more experience.

I upgraded from the A7Rii and wasn't sure it would be worth it at first. I'm really glad I did!!! First, the auto focus on this camera is so fast. Finally there is a high quality full frame mirrorless camera that can focus like a top end DSLR. Second, they improved the battery!!!

Although it has the same pixel count as the A7R II, the A7R III makes some significant improvements upon its predecessor. The handling is much improved by the addition of the Multi-Selector (mini-joystick) for setting the AF point.

High-quality full-frame 42Mp sensor; 10fps continuous shooting; Silent shutter possible at 10fps

Limited use made of the touch-screen; Complex menu that could still be better arranged; Only one SD slot is UHS-II compliant

Despite its relative newcomer status to serious digital photography, Sony has made huge strides to catch up with its veteran rivals – and the A7R III is testament to that. Taking all the good bits from previous A7 models (the OLED viewfinder, solid build, full-frame sensor), perfecting certain things and adding a host of new features, it’s a truly brilliant enthusiast camera that’ll handle any photo or video task you could put in front of it: wildlife, portraiture, landscape, street photography, filmmaking. Yes, it’s a seriously expensive product, but top products usually are. Just know that if you can find the money down the back of the sofa, you’ll be getting one of the finest cameras around in return.
