The Sony Alpha A7S II is a full-frame camera with a difference. Where its brother the A7R II uses a 42-megapixel sensor for massive amounts of detail, this camera pares the resolution all the way down to 12 megapixels to radically improve low-light performance.
Great low-light performance; Excellent for video; Much-improved ergonomics
Limited detail capture among full-frame cameras; Unimpressive burst performance
