Currently there are 3 native Standard Prime lenses for Fujifilm GFX 100 and all of these lenses are autofocus (AF) type.
GFX 100 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on GFX 100.
Since Fujifilm GFX 100 has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 3 Standard Prime lenses with Weather Sealings.
