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.
Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
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.
