X-A7vs A6400vs Sony A7R V
Which should you buy?
Beginner Fujifilm — X-A7 (2019): The most affordable X-mount entry — Fujifilm colour and film simulations with a large flip screen for beginners.
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.
Landscape, Studio & Commercial — Sony A7R V (2022): 61 megapixels and 8-stop IBIS in a weather-sealed body — the reference resolution camera for commercial and landscape professionals.
