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.
Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.
