Verdictwhich should you buy?
A6700 — All-Round & Video: Best-in-class autofocus and 4K/120p video in a compact APS-C body — the standout camera under £1,000.
A7S II — Low-Light Video, Documentary & Available-Light Filmmaking: 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.
