Sony Unveils Sony A7S III Camera: New Low-Light King?

Sony just introduced the long-awaited Sony A7S III mirrorless camera, which is designed for shooting photos and videos in extreme light without a flash. The Sony A7S III is the follow-up to the A7S II from 2015 and features an array of updates designed to improve on that camera, which had been dubbed the "Low-Light King" by some photographers and videographers.

Unlike the Canon EOS R5, which was announced earlier this month and can shoot uncropped 8K Raw video, the new Sony A7S III is limited to shooting 4K, but it offers 16-bit Raw video HDMI output for the first time in a Sony Alpha series camera. Whereas the Canon R5 sells for $3899, the Sony A7S III will retail for $3499 when it goes on sale in September 2020.

Here are some highlights of the just announced new Sony A7S III:

• Newly developed BIONZ XR image processing engine with what Sony says is eight times more processing power and a new 12.1-megapixel (approx., effective) back-illuminated full-frame Exmor R CMOS image sensor, designed to significantly reduce rolling shutter effect
