GearScore™ Verdict — Which should you buy?
Portrait, Street & Documentary Photography — GFX 50R (2018): The most portable GFX camera of its era — 51MP in a rangefinder-style body for photographers who want medium-format quality with a more discreet form.
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.
