Olympus M.Zuiko ED 25mm F1.2 PRO

A high-speed normal-length prime featuring an advanced optical design, the OM SYSTEM M.Zuiko Digital ED 25mm f/1.2 PRO Lens is a 50mm equivalent lens designed for Micro Four Thirds mirrorless cameras. Its unique 19 elements, 14 groups construction incorporates extra-low dispersion, aspherical, and high refractive index elements to significantly reduce both chromatic and spherical aberrations for notable image clarity, sharpness, and color accuracy. The lens is also characterized by a bright f/1.2 maximum aperture, which benefits working in low-light conditions and affords extensive control over depth of field. A nine-blade aperture is featured as well, to achieve a smooth bokeh quality when working with shallow depth of field techniques, and a Z Coating Nano has been applied to individual elements to limit flare and ghosting for improved contrast. Beyond the imaging assets, the lens' physical design is characterized by a weather-sealed construction to benefit working in harsh climates.
