Aldis' f7.7 Uno Anastigmat was available as convertible lens for still cameras. The front group of lens elements could be removed, leaving a single element as lens and the diaphragm on the camera. An optional alternate set of front lens elements named Uno Bi-Focal could be screwed upon that single element lens, giving an anastigmat of longer focal length than that the original Uno Anastigmat.
