GearScore™ Verdict — Which should you buy?
Professional Sports, Wildlife & Press Photography — EOS-1D X Mark III (2020): Canon's DSLR masterpiece — 20fps live view, 5.5K RAW, 191 cross-type AF points, and dual CFexpress. Almost certainly the finest optical viewfinder camera ever made.
Travel & Video — G85 (2016): The G85 is the definitive enthusiast MFT package — combining 4K/30p, Dual I.S. 2 stabilisation, and weather sealing in an affordable, well-built body. It lacks phase-detect AF (contrast-detect only) but covers travel, landscape, and casual video effectively. One of the best-value used-market MFT cameras available — a practical, capable companion for photographers who want reliability over cutting-edge specs.
