The A7 III hardly puts a foot wrong. Its specifications make it a terrific all-rounder, one that’s so powerful that its price is actually a bit of a surprise. Its handling and control layout aren’t perfect (fans might disagree!), but that’s soon forgotten in the face of its autofocus and continuous shooting performance, not to mention its 4K video capabilities.
The 24MP resolution might put a few people off. We’ve been spoiled recently by a slew of higher-resolution full-frame cameras like the Canon EOS 5DS, Nikon D850 and Sony’s own A7R III. Even the Pentax K-1 Mark II beats the A7 III, with its 36.4MP sensor.
But pixels aren’t everything, and 24MP is still enough to produce top-quality enlargements and meet most regular commercial briefs – and it’s what makes the A7 III’s amazing blend of speed, performance and value for money possible. Other cameras might grab the headlines in one area or another, but few are so consistently capable across such a wide range of disciplines.
Sony A7 III competition
Canon EOS 5D Mark IV
The EOS 5D Mark IV has a 30MP sensor, but its 4K video comes with a heavy crop factor and its continuous shooting speed is slower. It costs a whole lot more, too.
The D750 shows you can get cheaper 24MP full-frame cameras than the A7 III, but you don’t get 4K video or the A7 III's 10fps continuous shooting.
Sony A7R III
It’s a tricky choice. The A7R III wins by a mile for resolution, but the A7 III matches it elsewhere and beats it for autofocus options – and price!
