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.
Creative Filmmakers & Experimental Photographers — Sigma fp (2019): The smallest full-frame camera in the world — Cinema DNG RAW and L-mount flexibility in a pocket-sized body that rewards creative shooters.
