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.
Landscape, Studio & Commercial Photography — A7R III (2017): The camera that converted professionals to mirrorless — 42MP, IBIS, and 10fps in a body that still competes today.
