X-S20vs Lumix GH6vs A6400
Which should you buy?
Hybrid Photo & Video — X-S20 (2023): Fujifilm's most accessible X-series body — 7-stop IBIS, 6K video, 20 film simulations, and a user-friendly layout.
Video Creators & Documentary Filmmakers — Lumix GH6 (2022): The video-first MFT camera — 5.7K internal, unlimited record times, and 10-bit colour for professional video production.
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.
