The OM SYSTEM M.Zuiko Digital ED 12-100mm f/4 IS PRO Lens is a 24-200mm equivalent zoom designed for Micro Four Thirds mirrorless cameras. Characterized by its f/4 constant maximum aperture, this lens offers consistent performance throughout the zoom range to suit both stills and video shooting. Its optical design incorporates a slew of low dispersion and aspherical elements in order to reduce both chromatic and spherical aberrations, and both a ZERO coating and a Z Coating Nano have been applied to greatly reduce lens flare and ghosting for improved contrast.

Benefitting handling the expansive zoom range is an optical image stabilization system that works in conjunction with select cameras' 5-axis image stabilization to form Sync IS, which compensates for up to 6.5 stops of camera shake. A Movie & Still Compatible (MSC) high-speed imager AF system provides quick, accurate, and quiet focusing performance well-suited to both photo and video applications, and a manual focus clutch permits fast changing to MF for more precise control. Additionally, a lens function button is featured on the side of the barrel for direct settings adjustment, and the lens also features a weather-sealed construction for use in trying environmental conditions.
