GearScore™ Verdict — Which should you buy?
Hybrid Photography, Travel & Video On Sony Aps-C — A6600 (2019): The APS-C Sony that has everything — IBIS, real-time Eye AF, excellent battery life, and 4K/30p in a weather-sealed body.
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.
