GearScore™ Verdict — Which should you buy?
Casual & Everyday — EOS M100 (2017): The EOS M100 is Canon's most stripped-back EF-M camera — small, simple, and focused on making great photos easy. Dual Pixel AF, 24MP, and a tilting touchscreen are its strengths; no EVF, no IBIS, and no 4K are its compromises. A solid, affordable first mirrorless for casual photographers who want more than a smartphone.
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.
