Currently there are 35 native Wideangle Prime lenses for Leica SL2 and 27 of these lenses are autofocus (AF) type.
SL2 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on SL2.
Since Leica SL2 has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 20 Wideangle Prime lenses with Weather Sealings.
