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.

Dslr Enthusiasts & Outdoor Photographers — Pentax K-3 Mark III (2021): The finest APS-C DSLR ever made — class-leading weather sealing, optical viewfinder, 5-axis IBIS, and extraordinary build for photographers committed to DSLR.
