GearScore™ Verdict — Which should you buy?
Vlogging & Travel — PowerShot V1 (2025): The PowerShot V1 is Canon's best compact camera — a 1-inch stacked sensor, Dual Pixel CMOS AF, 4K/60p, built-in ND, and an articulating screen in a pocketable body. It is the compact camera Canon's content-creator audience has been waiting for, and a genuine step forward over the G7X series.
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.
