The deployment is manual, but facilitated by a foldable pull tab . The focusing  is done by extending the bellows, with a locking lever and a distance scale (in meters): 2, 3, 6, 10 and infinite ( ∞).
The shutter, which goes up to 1/100 , also offers slow speeds : 1 sec , 1/2 , 1/5 , 1/10 and 1/25 and 1/ 50. . It has two exposure mode referred to herein as 0 and Z (usually B and T). It is equipped with a pneumatic shutter speed adjustment .
