Currently there are 3 native Wideangle Zoom lenses for Panasonic S1H and all of these lenses are autofocus (AF) type.
S1H also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on S1H.
Since Panasonic S1H has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 2 Wideangle Zoom lenses with Weather Sealings.
