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 RP — Entry Full-Frame Stills Photography: An affordable gateway into the RF system. The RP makes sense as a stepping stone camera — if you're committed to Canon RF glass, this is the cheapest full-frame body to buy those lenses for. Just manage expectations on video and battery life.
