EOS M100vs A7R
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.
Studio, Tripod Landscape & Camera History — A7R (2013): The world's first 36MP full-frame mirrorless — a landmark camera that launched the A7R series, despite contrast-detect AF and significant shutter shock limitations.
