Fujifilm X100VIvs A6400vs A7 III
Which should you buy?
Street, Travel & Everyday — Fujifilm X100VI (2024): The best fixed-lens camera ever made — 40MP, 7-stop IBIS, film simulations, and a design icon. Wildly oversubscribed for good reason.
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.
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
