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.
Hybrid Video & Action — Z6 III (2024): Partial-stacked FF sensor for near-zero blackout, 6K RAW video, and 60fps burst — Nikon's most capable hybrid.
Creative Filmmakers & Experimental Photographers — Sigma fp (2019): The smallest full-frame camera in the world — Cinema DNG RAW and L-mount flexibility in a pocket-sized body that rewards creative shooters.
