Currently there are 17 native Standard Zoom lenses for Olympus E-M1 III and all of these lenses are autofocus (AF) type.
E-M1 III also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on E-M1 III.
Since Olympus E-M1 III has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 8 Standard Zoom lenses with Weather Sealings.
