S1 IIvs OM-5
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.
Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
