Olympus M.Zuiko Digital ED 12-100mm f/4 IS PRO Lens

Spanning a wide-angle to telephoto range; this 12-100mm zoom is designed for Micro Four Thirds mirrorless cameras and provides a 24-200mm equivalent focal length range. Constant f/4 maximum aperture provides consistent illumination throughout the zoom range to benefit both stills and video applications. One double-sided aspherical element and three aspherical elements are featured in the optical design to limit spherical aberrations for improved sharpness with reduced distortion. Additionally; five extra-low dispersion elements; two Super HR (high-refractive index) elements; and one HR element are also used to control chromatic aberrations and color fringing for greater clarity and color fidelity. Both a ZERO Coating and a Z Coating Nano are applied to individual lens elements to noticeable reduce surface reflections and prevent lens flare and ghosting for improved contrast and color neutrality in strong lighting conditions. Lens-based image stabilization helps to minimize the appearance of camera shake to benefit shooting handheld with this lens in difficult lighting conditions. Additionally; this lens supports Synchronized IS; which pairs the optical IS system with select Olympus cameras' 5-axis sensor-shift image stabilization to control up to 6.5 stops of camera shake. A MSC autofocus system provides quick; quiet; and precise focusing performance to benefit both still photo shooting and movie recording. Additionally; an MF clutch is used for fast changing to manual focus for more precise control. Weather-sealed construction guards the lens against dust and moisture for working in harsh environments. Circular seven-blade diaphragm contributes to a pleasing bokeh quality.
