This lens, of fixed focal lenght, meets many practical requirements and offers the great advantage of excellent handheld filmming. Its diaphragm can be closed completely. The long focusing range from infinity to 12cm (object-to-film plane), free working distance (object-to-front lens) about 3cm, and object field 36 x 27mm, permits filming of the most minute details in the close-up range without special attachments.
