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.
Adventure, Underwater & Outdoor Use — OM System TG-7 (2023): Waterproof to 15m, freezeproof and shockproof — the TG-7 is the most capable rugged compact for adventure and outdoor use.
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.
