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.
Dslr Enthusiasts & Outdoor Photographers — Pentax K-3 Mark III (2021): The finest APS-C DSLR ever made — class-leading weather sealing, optical viewfinder, 5-axis IBIS, and extraordinary build for photographers committed to DSLR.
