While the A7S III will certainly be a formidable video camera and will please those who have been waiting years for an update to the A7S II, it feels like Sony isn’t really pushing the envelope like it did with previous versions of the A7S.
Image: Sony The A7S III’s video resolution limits are a direct result of Sony’s decision to continue to use a 12-megapixel sensor in the camera.
Sony is apparently well aware of this lopsided comparison, so it is emphasizing the A7S III’s ability to shoot 4K video at up to 409,600 ISO, with over 15 stops of dynamic range.
So today, Sony is announcing the A7S Mark III, a familiar but refreshed version of its best mirrorless camera for video recording.
Sony is betting that we don’t, at least for now, and is confident that the A7S III will be the best 4K video camera in its segment.
