Sony A7 III Review: With outstanding image quality, the ‘basic’ Sony A7 III excels in every way

Описание к видео Sony A7 III Review: With outstanding image quality, the ‘basic’ Sony A7 III excels in every way

Replacing the four-year-old A7 II as the new entry-level model in Sony's full-frame line, the A7 III is an impressively capable camera that gives more expensive models a run for their money.

When it introduced the third-generation A7, Sony said the mirrorless camera would redefine what it meant to be the “basic” model — a promise that has largely been kept. The A7 has always been the entry point to Sony’s full-frame line, along with the higher-end A7R and A7S, and thus lacking some features. The A7 was never a beginner’s camera, by any means, but it is — or at least was — a compromise, seeking to appeal to a broader range of photographers without offering the more specific advantages of the A7R, A7S, or new A9 series.

The A7 III flips this notion on its head. It offers the dynamic range of the A7R III, the low-light performance of the A7S II, and enough of the A9’s speed that it serves up all the performance most of us would ever need — and it does it all for well below the cost of those other models. It is the complete package — the real deal, the full enchilada.

We have our usual reservations about Sony’s control layout and menu system, and the camera doesn’t achieve best-in-class status on every single feature, but it would be difficult not to recommend it to virtually any photographer who can afford it. Even those who could afford much more will likely find all the camera they need in the $2,000 A7 III.

Sony is known for pouring as much tech into its cameras as it can, and the A7 III is the latest example of this. It all starts with a new backside-illuminated (BSI) 24-megapixel sensor. The resolution hasn’t changed since the original A7, but backside illumination runs the circuity on the back of the sensor, rather than the front, making it more sensitive to light. This helps nudge the maximum ISO up a stop to 51,200 (which can be boosted to 204,800).

BSI sensors aren’t new, but the technique is generally reserved for sensors with smaller pixels — either tiny sensors like those in phones, or large sensors with very high pixel counts like the A7R III — where the difference is more noticeable. Sony’s move to a BSI sensor on the A7 III shows that it is trying to squeeze out as much as it possibly can from those 24 million pixels.

The A7 has always offered plenty of resolution for the majority of photographers, and by sticking with the same pixel count, Sony has been able to dramatically increase continuous shooting speed to 10 frames per second. Combined with a new autofocus system that puts 693 phase-detection points across nearly the entire frame, this should be an impressively capable camera for sports and action.
