Which should you buy?

Street, Documentary & Rangefinder Enthusiasts — Fujifilm X-Pro3 (2019): The most opinionated camera Fujifilm makes — a hidden screen and hybrid OVF enforce deliberate photography, rewarding photographers who slow down.

Hybrid Photo & Video — X-S20 (2023): Fujifilm's most accessible X-series body — 7-stop IBIS, 6K video, 20 film simulations, and a user-friendly layout.

Professional Video & Low-Light Filmmaking — A7S III (2020): If video is your primary discipline, the A7S III is the camera. 4K/120p at 10-bit in a weather-sealed body with a 9.44M dot EVF is an extraordinary package. The 12MP sensor isn't limiting for video — and it's usable at ISO 409,600 in a pinch.
