Currently there are 4 native Wideangle Zoom lenses for Fujifilm X-T1 IR and all of these lenses are autofocus (AF) type.
Fujifilm X-T1 IR doesn't have a sensor based image stabilization system but 2 of these Wideangle Zoom lenses features optical image stabilization.
Since Fujifilm X-T1 IR has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 3 Wideangle Zoom lenses with Weather Sealings.
