Currently there are 24 native Telephoto Zoom lenses for Panasonic G97 and all 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 15 Telephoto Zoom lenses with Weather Sealings.
