Currently there are 2 native Wideangle Zoom lenses for Nikon Z50 and all of these lenses are autofocus (AF) type.
Nikon Z50 doesn't have a sensor based image stabilization system and none of these lenses have optical Image Stabilization.
Since Nikon Z50 has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 2 Wideangle Zoom lenses with Weather Sealings.
