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.
Portrait & Wedding Photography — A7 IV (2021): The full-frame portrait benchmark — 33MP, AI Eye AF, and exceptional skin-tone rendering in a pro-grade hybrid body.
