Chinese lens manufacturer Jakumei Optics has announced (translated) the release of the Dulens APO 85mm F2 manual lens for Canon EF- and Nikon F-mount camera systems.
According to the manufacturer, the lens’ apochromatic (APO) design is inspired by ‘Sonnar-style’ lenses, the first of which was created by Dr. Ludwig Bertele in 1929.

The lens is constructed of seven elements in six groups, including two extra-low dispersion elements and one high-refractive index lens. Other features include an aperture range of F2-F16, a nine-blade aperture diaphragm, a 90cm (3ft) minimum focusing distance and a 55mm front filter thread.
