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 & Photojournalism — A9 II (2019): The A9 II polished the A9's groundbreaking formula — 20fps blackout-free, improved subject tracking, and a LAN port made it the professional sports standard.
