Currently there are 13 native Telephoto Prime lenses for Panasonic G97 and 7 of these lenses are autofocus (AF) type.
G97 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on G97.
Since Panasonic G97 has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 4 Telephoto Prime lenses with Weather Sealings.
