GearScore™ Verdict — Which should you buy?

Canon Mirrorless History & Ef-M Collectors — EOS M (2012): Canon's first mirrorless — a historic body that broke new ground with touch-AF and EF-M, but its sluggish contrast-detect system quickly became its Achilles heel.

Sports & Photojournalism Professionals — Canon EOS R3 (2021): The pinnacle of Canon's mirrorless lineup for speed — Eye Control AF and 30fps burst in the most rugged body Canon has ever produced.

Travel & Vlogging — PowerShot G7X Mark II (2016): The G7X Mark II is one of the most popular compact cameras ever made — and for good reason. A fast f/1.8-2.8 lens, 20MP 1-inch sensor, flip-up selfie screen, and Micro USB charging combine in one of the most vlog-friendly compact cameras available. No 4K and no EVF are the main compromises, but the G7X II remains outstanding value on the used market.
