Fujifilm X100VIvs Nikon Z9vs A6400
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.
Professional Sports & Wildlife — Nikon Z9 (2021): The Z9 redefined what professional mirrorless could be — no mechanical shutter, 45MP stacked BSI, and 8K RAW in the most rugged Z body.
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.
