GearScore™ Verdict — Which should you buy?

Groups, Landscapes & Anyone Who Wants Bigger Prints — Instax Wide 400 (2022): The Wide format transforms instant photography — larger prints with proper presence. The right choice for groups and landscapes.

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.
