Sony Alpha a7 III Review

Sony Alpha a7 III

Sony has filled the last gap in its full-frame lineup with the A7 III. With a newly developed full-frame 24.2-megapixel back-illuminated Exmor R CMOS image sensor, the same advanced autofocus engine found on the lauded A9 and A7R III, and 10 frames per second (even in fully silent shooting mode), there is quite a lot to unpack with Sony’s latest professional mirrorless camera. Some might be tempted to label it “prosumer,” but it may just challenge how robust a camera can be and still be given that moniker.

The Alpha A7 III sits on the bottom rung of Sony’s full-frame mirrorless camera range and is designed to appeal to both keen enthusiast photographers and professionals.

In the past the A7 series of cameras have always felt like poor relations to the A7R and A7S series. While the latter two ranges have tended to capture the limelight with their high pixel counts and advanced video capabilities, the A7 cameras have always been regarded as the basic models, sporting a solid but unremarkable set of features.

Summary
The Alpha A7 III is a brilliant camera that ticks a lot of boxes for many photographers. Sony has taken some of the best bits from its flagship Alpha A9 and A7R III, and distilled them into a single camera that offers a fantastic mix of performance and image quality. For the price, there's nothing that can touch it.
