Fujifilm X-T4vs Lumix S5vs Sony A9 III
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.
Sports & Action Professionals — Sony A9 III (2023): A paradigm-shifting camera — the global shutter eliminates every rolling shutter limitation that has constrained action photography for years.
