Verdictwhich should you buy?

GFX 100 — Commercial, Studio & Landscape Photography: 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.

A1 — Professional Sport, Wildlife, Portrait & Hybrid Shooting: 50MP, 30fps, 8K — the Sony A1 is the most complete professional camera ever made.
