Verdictwhich should you buy?

EOS-1Ds — Full-Frame Dslr History & Canon Archive Collections: The world's first production full-frame DSLR — the EOS-1Ds arrived in 2002 with 11MP and changed professional photography forever. Historically irreplaceable.

EOS M100 — Casual & Everyday: 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.
