EOS M3vs A7 V
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.
Portrait, Wedding, Travel, Video — A7 V (2024): The definitive full-frame mirrorless. Hard to argue for anything else at this price.
