EOS R8vs Nikon D7500vs A6400
Which should you buy?
Full-Frame Entry — EOS R8 (2023): Canon's most affordable full-frame mirrorless — 4K/60p 10-bit and class-leading Dual Pixel AF at an accessible entry price.
Sports, Travel & Dslr Shooters — Nikon D7500 (2017): The D500's BSI sensor in a compact, weather-sealed body — excellent high-ISO performance and DSLR reliability at a great price.
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.
