M.Zuiko 12-45mm f/4 PRO

The OM SYSTEM M.Zuiko Digital ED 12-45mm f/4 PRO is a compact wide-angle zoom lens designed for Micro Four Thirds mirrorless cameras, covering a 24-90mm equivalent focal length range. The lens maintains a constant f/4 maximum aperture throughout its zoom range, balancing brightness with a lightweight form factor of just 254 grams. The optical design incorporates aspherical elements, extra-low dispersion glass, and high-refractive index elements to minimize spherical aberrations, color fringing, and distortion while maintaining sharp, color-accurate imagery.

The lens features a ZERO coating on individual elements to suppress flare and ghosting for improved contrast in bright conditions, and its Movie & Still Compatible autofocus system provides fast, smooth, and silent focusing performance suitable for both photography and video work. With a minimum focusing distance as close as 4.7 inches at the wide end and a 0.25x maximum magnification, the lens is capable of close-up work. The lens is also weather-sealed against dust, freezing temperatures, and drips for use in challenging environmental conditions.
