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 M50 — Casual & Vlogging: The EOS M50 is the most complete-feeling entry-level EF-M camera — built-in EVF, fully articulating screen, Dual Pixel AF, and a well-designed compact body. Its 4K video carries a significant crop and loses Dual Pixel AF, making 1080p the practical option — but for stills and casual video, it remains an excellent used-market buy.
