4.2 Focusing 

 
Set the aperture by rotation of the ring 5 (fig.2) until superposition of the selected value with the index on the fixed ring occurs. For 

full opening of the aperture (during image focusing) turn the ring 4 clockwise (if you look from the camera’s side) up to the stop. When 
photographing the subject while not interrupting to monitor the image in the camera viewfinder’s vision field, turn the ring 4 counter-
clockwise up to the stop or press the wire’s button screwed into the seat 6 – after that selected value of aperture will be set. Then press 
the release button on the camera.

4.3. Aperture operation 

 
Focusing is done at maximum aperture by rotating focusing ring 3 with focusing scale until you receive a clear image of the subject 

as observed in the viewfinder. 

Focusing scale 2 serves as a secondary focusing aid if the approximate distance to the subject is known.  
The depth of field is determined by the focal distance using additional scale and viewed by the subject’s image details on the matte 

groundglass surface in the viewing field of the viewfinder by rotating ring 4 counter-clockwise (if you look from the camera’s side) up to 
the stop. 

 
 

4.4. Lens shifting 
 

The lens optical block shift is performed by rotating ring 1 with the shift scale (in millimeters). The maximum axis shift (figure 3) 

corresponds to the ring 1 turn (figure 2) by 90°. The direction of the shift is selected by rotating the lens in relation to the bayonet axis. 

To rotate the lens pull aside locking button 7 towards the camera. The lens can then be rotated around the bayonet axis by 360° 

and locked at every 15° interval.
