Verdictwhich should you buy?

EOS-1D — Professional Digital Camera History Collectors: Canon's first pro digital DSLR — a 4MP, 8fps APS-H monster from 2001 that set the template for every 1D to follow. A landmark piece of digital camera history.

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.
