Currently there are 20 native Telephoto Prime lenses for Panasonic S1 II and 19 of these lenses are autofocus (AF) type.
S1 II also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on S1 II.
Since Panasonic S1 II has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 13 Telephoto Prime lenses with Weather Sealings.
