Which should you buy?
Vloggers & Content Creators — Canon PowerShot V10 (2023): A vlog-first compact with a 1-inch sensor, front-facing screen, and Canon's Dual Pixel AF — the simplest way to create clean content on the go.
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.
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.
