Verdictwhich should you buy?

EOS R6 Mark III — Hybrid Photo & Video Professionals, Sports And Wildlife Shooters: 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.
