Fujifilm X-T4vs Z5 IIvs A6400
Which should you buy?
Hybrid Shooters & Enthusiasts — Fujifilm X-T4 (2020): The X-T series reached hybrid maturity with the X-T4 — IBIS, 4K/60p, and Fujifilm colour science in the most complete X-T package.
Full-Frame Value — Z5 II (2024): The most accessible full-frame mirrorless — dual card slots, weather sealing, and Nikon colour at a sensible price.
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.
