EOS R8vs A6400vs Sony RX100 VII
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.
Travel & Versatility — Sony RX100 VII (2019): The most versatile compact camera ever made — 24-200mm zoom, 20fps burst, and 960fps slow-motion in a jacket pocket.
