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.

A6400 — Content Creation & Vlogging: The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
