The lens is of preset design, although rumors of a manual version exist. It was released in September 1952, and listed into 1961. One example has been found finished partially in a black crinkle finish. Most are finished in a smooth black. Other than that, there are no variations in the approximate 300 examples produced. Serial numbers run from 647001 to 6472xx.
This lens, like all of the short mount lenses, require the reflex housing for use.
