Offering long reach with an advanced feature set and optical design, the M.Zuiko Digital ED 40-150mm f/2.8 PRO Lens from OM SYSTEM 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.
Optical Design and Features
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 lens coating reduces flare and ghosting for high-contrast, colour-accurate imaging.
Autofocus and Control
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 a programmable L-Fn button avails lens-based control over shooting settings.
Weather Sealed and Tripod Support
The lens is also weather sealed for working in trying conditions, and a rotating tripod collar is included for improved balance and support when working atop a tripod or monopod.
