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.
Travel, Landscape & Portrait Photography With Minimal Kit — A7CR (2023): The world's smallest 61MP full-frame camera — A7R V quality in a pocketable A7C body.
