Currently there are 3 native Wideangle Zoom lenses for Sigma fp and all of these lenses are autofocus (AF) type.
Sigma fp doesn't have a sensor based image stabilization system and none of these lenses have optical Image Stabilization.
Since Sigma fp has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 2 Wideangle Zoom lenses with Weather Sealings.
