Quick Overview A new era optical design lens with an exceptionally bright maximum aperture, the Olympus M.Zuiko Digital ED 17mm f/1.2 PRO is an adaptable wide-angle lens with 34mm-equivalent prime for Micro Four Thirds mirrorless cameras. The lens's key feature is its fast f/1.2 maximum aperture, which is suitable for working in difficult lighting conditions. Also inbuilt with a complex 15 elements, 11 group’s construction gives extra-low dispersion, aspherical, and high refractive index elements to degrade both chromatic and spherical aberrations for notable image clarity, sharpness, and color accurate image. A nine-blade aperture is featured inside to achieve a smooth pixel quality when working in the shallow depth of field techniques, and a Z Coating Nano has been applied to every individual element of the lens to limit flare and ghosting for improved contrast. Beyond the imagination, the lens's sleek design is characterized by a weather-resistant quality to give you access to working in harsh and difficult climate situations. It also features an MSC autofocus system for smooth, quiet, and fast focusing performance that is suitable for both stills and video recording.
