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 R100 — First Camera / Beginner Photography: The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
