Bright and sleek, the black Speedmaster 17mm f/0.95 from Mitakon Zhongyi is a unique wide-angle prime for Micro Four Thirds mirrorless cameras. This 34mm-equivalent lens is distinguished by its impressive f/0.95 maximum aperture, which excels in low lighting and also helps to control depth of field for isolating subject matter using selective focus. An optimized optical design also helps to render imagery with a high degree of sharpness and clarity and a rounded eight-blade diaphragm contributes to a pleasing bokeh quality.

The physical construction of the lens revolves around its manual focus design, which is complemented by printed depth of field and distance scales for zone focusing techniques. The manual aperture ring also features a click-less design for silent, smooth operation that is beneficial to video recording applications.
