GearScore™ Verdict — Which should you buy?
Video, Filmmaking & Hybrid Shooting — GH5 (2017): The GH5 redefined what a consumer video camera could do — 4K/60p and 10-bit 4:2:2 internal recording made it the independent filmmaker's tool of choice for years.
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.
