GearScore™ Verdict — Which should you buy?
Casual & Everyday — EOS M3 (2015): The EOS M3 was a meaningful upgrade over the original EOS M — bringing 24MP, a tilting touchscreen, and improved Hybrid CMOS AF III. Video tops out at 1080p/30p and burst shooting is modest, but for stills photographers wanting affordable APS-C quality, the M3 is a competent used-market option.
Professional Sport, Wildlife, Portrait & Hybrid Shooting — A1 (2021): 50MP, 30fps, 8K — the Sony A1 is the most complete professional camera ever made.
