EOS RPvs Z6 IIvs A6400
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.
All-Round Full-Frame Photography — Z6 II (2020): The Z6 II is the Nikon most photographers should buy. It's balanced across every discipline — stills, video, autofocus, weather sealing — without overpaying for megapixels you don't need. The Z-mount glass is superb.
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.
