X-A7vs Nikon Z8vs A6400
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.
Sports, Wildlife & Hybrid Professionals — Nikon Z8 (2023): Z9 performance in a compact body — 45MP, 8K/60p RAW, and 20fps burst without the bulk or price of the flagship.
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.
