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.
Professional Sports, Wildlife & Photojournalism — EOS R1 (2024): Canon's ultimate professional camera — 40fps, a class-leading EVF, and AI AF that simply doesn't miss.
Hybrid Photo & Video Professionals, Sports And Wildlife Shooters — EOS R6 Mark III (2025): The EOS R6 Mark III takes everything that made the Mark II a hybrid favourite and pushes it further — a faster stacked sensor, smarter autofocus, and genuinely professional video specs. It's the most complete all-rounder in Canon's RF full-frame lineup, sitting just below the R5 II in resolution while matching it for speed.
