Currently there are 6 native Wideangle Zoom lenses for Olympus E-M5 II and all of these lenses are autofocus (AF) type.
E-M5 Mark II also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on E-M5 Mark II.
Since Olympus E-M5 II has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 4 Wideangle Zoom lenses with Weather Sealings.
