EOS RPvs A6400vs Sony A7R V
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.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
Landscape, Studio & Commercial — Sony A7R V (2022): 61 megapixels and 8-stop IBIS in a weather-sealed body — the reference resolution camera for commercial and landscape professionals.
