GearScore™ Verdict — Which should you buy?
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.
Professional Video, Documentary & Cinematic Filmmaking — FX3 (2021): The definitive run-and-gun cinema camera — A7S III sensor quality in a body built specifically for video professionals.
