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.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
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.
