EOS M3vs OM-1
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.
Wildlife, Sport, Outdoor — OM-1 (2022): OM System's statement camera — class-leading weather sealing and the best IBIS in the business.
