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.
Dslr Enthusiasts & Outdoor Photographers — Pentax K-3 Mark III (2021): The finest APS-C DSLR ever made — class-leading weather sealing, optical viewfinder, 5-axis IBIS, and extraordinary build for photographers committed to DSLR.
