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.
Hybrid Shooters & Professionals — Canon EOS R5 Mark II (2024): The most complete hybrid camera Canon has ever made — 45MP stacked BSI, 30fps burst, 8K/60p RAW, and Canon's legendary Dual Pixel AF in one body.
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.
