GearScore™ Verdict — Which should you buy?
Professional Sports, Wildlife & Photojournalism — EOS R1 (2024): Canon's ultimate professional camera — 40fps, a class-leading EVF, and AI AF that simply doesn't miss.
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.
