Olympus has expanded its advanced PRO lens lineup with two fast and enticing primes, the M.Zuiko Digital ED 17mm f/1.2 PRO and the M.Zuiko Digital ED 45mm f/1.2 PRO. Characterized by their sophisticated optical designs, robust build quality, and impressive speed, these two additions continue to round out the PRO-series of high-performance lenses for the ever-expanding Micro Four Thirds system.
Looking at the wide-angle option first, the M.Zuiko Digital ED 17mm f/1.2 is a 34mm equivalent prime, making for a comfortable and versatile focal length for working in a variety of situations. Its f/1.2 maximum aperture benefits shooting in difficult lighting conditions and allows you to achieve desirable selective focus effects. The complex optical design contains a variety of low dispersion, aspherical, and high refractive index glass elements to reduce chromatic and spherical aberrations and distortion noticeably, for high sharpness and clarity throughout the aperture range. A Z Coating Nano has also been applied to suppress flare and ghosting for greater contrast and color accuracy. Like other PRO lenses, this 17mm f/1.2 also sports an MSC autofocus system and manual focus clutch for quick changing between focusing methods, and a printed depth-of-field scale is on the barrel for working with zone focusing and pre-focusing techniques.
At the other end of the focal length spectrum is the 90mm equivalent M.Zuiko Digital ED 45mm f/1.2 PRO, which stands as an ideal lens for portraiture due to its slightly narrower field of view and ability to easily isolate subject matter. The f/1.2 maximum aperture again allows this lens to excel in low light and affords great control over depth of field. A similarly impressive optical design is featured, too, and employs a series of extra low dispersion, aspherical, and high refractive index glass elements, as well as a Z Coating Nano, to produce well-corrected imagery. Other traits shared between both lenses include a programmable L-Fn button on the lens barrel for easy lens-based settings adjustment, a rounded nine-blade diaphragm for smooth bokeh quality, and a weather-sealed design to permit working in harsh weather conditions.
