Verdictwhich should you buy?
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.
FX3 — Professional Video, Documentary & Cinematic Filmmaking: The definitive run-and-gun cinema camera — A7S III sensor quality in a body built specifically for video professionals.

EOS RP (2019)
is the right camera for you if…
