GearScore™ Verdict — Which should you buy?
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.
Professional Sports & Wildlife — Nikon Z9 (2021): The Z9 redefined what professional mirrorless could be — no mechanical shutter, 45MP stacked BSI, and 8K RAW in the most rugged Z body.
