GearScore™ Verdict — Which should you buy?
Professional Sports, Wildlife & Press Photography — EOS-1D X Mark III (2020): Canon's DSLR masterpiece — 20fps live view, 5.5K RAW, 191 cross-type AF points, and dual CFexpress. Almost certainly the finest optical viewfinder camera ever made.
Full-Frame Entry — EOS R8 (2023): Canon's most affordable full-frame mirrorless — 4K/60p 10-bit and class-leading Dual Pixel AF at an accessible entry price.
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.
