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.

Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
