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.
High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.
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.
