GearScore™ Verdict — Which should you buy?
Portrait & Street — EOS M6 Mark II (2019): 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.
Sports & Action Professionals — Sony A9 III (2023): A paradigm-shifting camera — the global shutter eliminates every rolling shutter limitation that has constrained action photography for years.
