Verdictwhich should you buy?
EOS M3 — Casual & Everyday: 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.
EOS M6 Mark II — Portrait & Street: The M6 Mark II is the peak of the EF-M system — 32.5MP, 14fps, and Dual Pixel CMOS AF II in a compact rangefinder-style body. No built-in EVF is the main compromise, but the optional EVF-DC2 resolves this. An outstanding used-market buy for photographers who want high resolution and fast AF in a genuinely compact body.
