GearScore™ Verdict — Which should you buy?
All-Round & Video — A6700 (2023): Best-in-class autofocus and 4K/120p video in a compact APS-C body — the standout camera under £1,000.
Low-Light Video, Documentary & Available-Light Filmmaking — A7S II (2015): A landmark in mirrorless history — the first Sony with IBIS and internal 4K, its low-light video capability still impresses today at a used-market price.
