Which should you buy?
Sports, Wildlife & Dslr Enthusiasts — Canon EOS 90D (2019): The best APS-C DSLR Canon ever made — 32MP, 10fps, weather sealing, and an optical viewfinder experience no mirrorless can replicate.
Entry Full-Frame Stills Photography — EOS RP (2019): 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.
Wildlife, Birds & Outdoor Sports — OM System OM-1 Mark II (2024): OM System's most capable camera — 120fps AF burst, AI subject detection, and IP53 weather sealing make it the best-value pro wildlife camera.
