GearScore™ Verdict — Which should you buy?
Commercial, Studio & Landscape Photography — GFX 100 (2019): The world's first 100MP mirrorless with IBIS and phase-detect AF — the GFX 100 was a landmark in medium format, but its size and weight are professional-grade.
Wildlife, Birds & Outdoor Sports — OM System OM-1 Mark II (2024): OM System's most capable camera — 120fps AF burst, AI subject detection, and IP53 weather sealing make it the best-value pro wildlife camera.
