Which should you buy?
Adventure, Outdoor Sports & Action — DJI Action 5 Pro (2024): DJI's best action camera — 4K/120p from a large 1/1.3" sensor, 20m waterproofing without a housing, and the best EIS stabilisation in any action camera.
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.
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.
