Sony's most affordable full-frame camera is certainly nothing to scorn at.

Class-leading picture quality, enhanced usability, sharp 4K-video, and fast shooting rate and focus response.

Low resolution viewfinder and display, moderate weather proofing, and only one UHS-II slot.

Sony's 24.2-megapixel A7 III is a near-perfect all-around mirrorless camera. You can fire bursts at 10 fps, capture sharp images with excellent dynamic range day or night, and autofocus accurately on fast-moving subjects or portraits.

Stellar low-light/high ISO capability; Much-improved handling; Fast 10 fps shooting; Excellent autofocus; Sharpest 4K video of any Sony full-frame camera; Double the battery life of the last model

EVF and viewfinder not quite as good as rivals; Two SD card slots but only one is high-speed UHS-II; Not as weather-resistant as the Fujifilm's X-H1; No 10-bit video output like Panasonic's GH5s

The Sony Alpha A7 III is a feature packed and highly versatile body that sets a new benchmark for "entry-level" full-frame cameras. At $1,999, it's not exactly cheap, but for serious enthusiasts and even professional photographers, the A7 III offers a rich feature set at a reasonable price point.

It's hard to believe that Sony's A7-series has been in existence for well over four years now. It feels like only yesterday the manufacturer presented us with the original A7 and A7R , yet here we're looking at the third release of its most basic full-frame mirrorless camera, which advances in a...

Excellent value for money; Improved battery stamina; Fast and responsive autofocus system; Revised button layout for intuitive control

AF point illumination could be improved; Convoluted menu system; Thin plastic port covers aren't weather-sealed; Handles poorly with large gloves in cold climates

The Sony Alpha7 III digital camera is an amazing device, managing to stuff a full frame sensor into a remarkably compact body. Capturing detail in a bright object (such as a fifty carat pink diamond) against a black background called for some exposure compensation.

Fast accurate photography; superb sensor; excellent exposure tuning

Display screen not touch sensitive, few trick modes (eg; time lapse, stop motion), slow battery charge

As it was launched in February 2018, the Sony A7 III is getting on a bit but it remains an excellent all-rounder. Its high-quality 24Mp full-frame sensor delivers superb images in a wide range of conditions and its viewfinder and screen provide a good preview so you know what you're going to get...

Good-quality 24Mp full-frame sensor; Excellent autofocus system; Attractively priced in the full-frame market

Minimal use of the screen's touch-sensitivity; Tilting rather than vari-angle screen; Complex menu

Put simply, the Sony a7 III is a new benchmark for full frame cameras due to its compelling combination of value and capability – and the fact that this series of cameras has come so far in less than five years is impressive in its own right.

Generalist photographers; wedding; event and action shooters and those that need high quality video

Those that need more resolution for detailed scenes or large prints; those that need ultimate build quality for harsh shooting conditions

Until now, Sony has been the only mirrorless camera manufacturer to offer cameras with ‘full-frame' sensors; but that's about to change. On 23 August Nikon will unveil its first mirrorless camera, which will have a full-frame sensor and a new lens mount.

Even if you can afford more, you'll find everything you need in the A7 III.

Exceptional image quality; 10 fps continuous shooting; 693-point AF system; Very responsive performance; Very good 4K video

Frustrating menu and control layout; 2.36-million-dot EVF is behind the times; Video is no longer best in class

I bought this camera to explore the exciting developments in auto focusing. Compared to previous Sony models, and to other manufacturers' models, the A7iii is so much better. But the big let down is the awful menu. Where do you find all the settings to get the most out of the auto focusing

Eye focus brilliant; portraits could be pinsharp; Great Picture Quality; The Auto focus system is stunning

Awful menu Organisation; Flimsy Construction
