EOS R7vs OM-1 IIvs A6400
Which should you buy?
Wildlife, Sports & Action — EOS R7 (2022): The EOS R7 is one of the most complete APS-C cameras ever made. It combines a class-leading resolution sensor with best-in-class IBIS, 4K/60p video, weather sealing and 15fps burst. For wildlife, sports and action photographers on an APS-C budget, nothing else comes close.
Wildlife & Action — OM-1 II (2024): 120fps burst, 8-stop IBIS, and IP53 sealing — the most capable wildlife and action camera in the Micro Four Thirds world.
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.
