Currently there are 15 native Standard Prime lenses for Panasonic GH5 II and 10 of these lenses are autofocus (AF) type.
GH5 II also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on GH5 II.
Since Panasonic GH5 II has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 3 Standard Prime lenses with Weather Sealings.
