GearScore™ Verdict — Which should you buy?
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.
Creative Filmmakers & Experimental Photographers — Sigma fp (2019): The smallest full-frame camera in the world — Cinema DNG RAW and L-mount flexibility in a pocket-sized body that rewards creative shooters.
