Currently there are 2 native Wideangle Zoom lenses for Fujifilm GFX 100S and all of these lenses are autofocus (AF) type.
GFX 100S also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on GFX 100S.
Since Fujifilm GFX 100S has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 2 Wideangle Zoom lenses with Weather Sealings.
