Which should you buy?
Vloggers, Travellers & Content Creators — DJI Osmo Pocket 3 (2023): A 1-inch sensor on a 3-axis gimbal in a palm-sized body — the Osmo Pocket 3 makes cinematic stabilised footage as simple as pressing record.
Portrait & Wedding Photography — A7 IV (2021): The full-frame portrait benchmark — 33MP, AI Eye AF, and exceptional skin-tone rendering in a pro-grade hybrid body.
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.
