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.
Wildlife, Birds & Outdoor Sports — OM System OM-1 Mark II (2024): OM System's most capable camera — 120fps AF burst, AI subject detection, and IP53 weather sealing make it the best-value pro wildlife camera.
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.
