The M.Zuiko Digital ED 40-150mm f/2.8 PRO from Olympus is a versatile 80-300mm equivalent telephoto zoom for Micro Four Thirds mirrorless cameras. As part of the PRO series of advanced lenses, this zoom distinguishes itself with a bright f/2.8 constant maximum aperture for consistent illumination throughout the zoom range to suit working in a variety of lighting conditions. Its optical design makes use of a series of aspherical and low dispersion glass elements to suppress chromatic and spherical aberrations for notable sharpness and clarity, and a ZERO coating is also used to reduce flare and ghosting for high contrast, color-accurate imaging.
Complementing the optics, a dual VCM autofocus system offers fast and near-silent focusing performance to suit both stills and movie recording applications. A manual focus clutch permits quick switching between AF and MF, and programmable L-Fn button avail lens-based control over shooting settings. The lens is also weather-sealed for working in trying conditions, and a removable rotating tripod collar is included for improved balance and support when working atop a tripod or monopod.
