The black M.Zuiko Digital ED 75mm f/1.8 Lens from Olympus is a beautiful high-quality medium length telephoto lens (equivalent to 150mm in 35mm or full-frame format) for Micro Four Thirds format cameras. The large f/1.8 maximum aperture makes it a natural for shallow depth of field focusing and low-light situations. Its 9-blade diaphragm provides pleasing bokeh.

This is a small (2.7 x 2.5") lens that weighs only 10.7 oz, despite having 10 elements in 9 groups. The fast, quiet MSC (Movie & Still Compatible) autofocus mechanism makes this a great choice for shooting video as well as stills. The precision-touch metallic focus ring delivers firm, easy manual focusing, as well. There are three ED (Extra-low Dispersion) elements that correct aberrations to a large degree, and Olympus’s ZERO (ZUIKO Extra-low Reflection Optical Coating) lens coatings reduce reflectance to as little as half that of conventional coatings by minimizing ghosting and flare.
