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.
Hybrid & Video — S1 II (2025): The S1 II is the full-frame L-mount hybrid camera Panasonic's system has been waiting for — phase-detect AF, 4K/120p, class-leading IBIS, and a professional build in one complete package. It addresses every weakness of the original S1 and positions Lumix firmly back in the conversation for serious hybrid shooters.
