Fujifilm X-T4vs Lumix S5vs 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.
Professional Video & Hybrid Shooting — Lumix S5 (2020): The S5 is an outstanding video camera that also takes excellent stills. 10-bit 4K/60p, dual native ISO and 6.5-stop IBIS in a weather-sealed body is a compelling package. The contrast-detect AF is its main weakness vs Sony and Canon — but for controlled shooting it doesn't hold it back.
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.
