GearScore™ Verdict — Which should you buy?
Professional Video, Documentary & Hybrid Commercial Work — EOS R5 C (2022): Canon's R5 reborn for cinema — 8K RAW unlimited, Cinema EOS colour science, and 45MP stills 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.
