EOS R8vs A6400vs Sony FX30
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.
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.
Video Creators & Filmmakers — Sony FX30 (2022): The Cinema Line entry point — S-Cinetone colour science, 4K/120p, and XLR audio in a compact, affordable body that punches far above its price.
