Olympus M.Zuiko Digital 12-100mm f/4 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 (high-refractive index) elements, and one element are also used to control chromatic aberrations and color fringing for greater clarity and color fidelity. Both a 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 , which pairs the optical system with select Olympus cameras' 5-axis sensor-shift image stabilization to control up to 6.5 stops of camera shake. A autofocus system provides quick, quiet, and precise focusing performance to benefit both still photo shooting and movie recording. Additionally, an 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.
