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.
Video, Independent Filmmaking & Documentary — GH4 (2014): The world's first consumer 4K camera — the GH4 changed independent filmmaking and proved that broadcast-quality video didn't require a cinema camera budget.
