Currently there are 16 native Wideangle Zoom lenses for Sony A7S III and 15 of these lenses are autofocus (AF) type.
A7S III also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on A7S III.
Since Sony A7S III has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 15 Wideangle Zoom lenses with Weather Sealings.
