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.
Landscape, Studio & Commercial Photography — A7R III (2017): The camera that converted professionals to mirrorless — 42MP, IBIS, and 10fps in a body that still competes today.
