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.
Portrait, Landscape & Studio Photography — A7R II (2015): The A7R II transformed the A7R series — adding IBIS, 4K video, BSI sensor tech, and phase-detect AF in one generation. A landmark Sony camera.
