Olympus M.Zuiko Digital ED 40-150mm F2.8 PRO is a versatile 80-300mm equivalent telephoto zoom lens for Micro Four Thirds mirrorless cameras. As part of the PRO series of advanced lenses, this zoom lens is distinguished by a bright constant maximum aperture of F2.8 that allows it to work in a variety of lighting conditions. Its optical design makes use of a series of aspherical and low-dispersion glass elements, in fact eliminating chromatic and spherical aberrations while achieving sharpness and clarity. In addition, a ZERO coating reduces flare and ghosting for high contrast and accurate color.

Complementing the optics of the Olympus M.Zuiko Digital ED 40-150mm F2.8 PRO lens, a dual VCM autofocus system offers fast and near-silent focusing performance to suit both still and movie recording applications. A manual focus clutch allows quick switching between AF and MF, and a programmable L-Fn button offers lens-based control over shooting settings. The lens is built to work in tough conditions, and a removable rotating tripod collar is included for better balance and support.
