Currently there are 20 native Telephoto Prime lenses for Panasonic S1H and 19 of these lenses are autofocus (AF) type.
S1H also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on S1H.
Since Panasonic S1H has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 13 Telephoto Prime lenses with Weather Sealings.
