Currently there are 5 native Telephoto Prime lenses for Leica SL and all of these lenses are autofocus (AF) type.
Leica SL doesn't have a sensor based image stabilization system and none of these lenses have optical Image Stabilization.
Since Leica SL has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 4 Telephoto Prime lenses with Weather Sealings.
