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.
Professional Sports, Wildlife & High-Resolution Studio Work — A1 II (2025): The most complete camera ever made — 50MP, 30fps, 8K, and the world's best EVF in a single flagship body.
