Which should you buy?
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, Sports & Hybrid Mft Shooters — Lumix G9 II (2023): Phase-detect AF transforms the G9 II into a genuine MFT all-rounder — the best Lumix MFT camera for both stills and video.
Portrait & Wedding Photography — A7 IV (2021): The full-frame portrait benchmark — 33MP, AI Eye AF, and exceptional skin-tone rendering in a pro-grade hybrid body.
