central index mark 6 of fixed ring 3 will come along the camera vertical axle.
If you are going to shoot with a light filter, unscrew the light filter compensator 4 and replace it with a light
filter you have selected screwing it into the lens as far as it will go. Shooting over, replace the light filter with
the compensator screwing it into the lens as far as it will go.

Operating Procedure
Before taking pictures remove the lens front cap.
Set the selected aperture on scale 2 against central index 6 on fixed ring 3. By rotating ring 1 focus the lens at
the object to be photographed so that the image will be sharp in the view-finder. Focusing should be done at
fully open diaphragm. On pressing the camera release button the lens automatic diaphragm will close down to
a selected aperture and the shutter will fire. Shutter firing over, the diaphragm will restore to initial position.
When photographing groups of objects in different distances from the camera, make use of depht-of-field scale
3. Index marks on the depht-of-field scale, corresponding to the set aperture value, will indicate sharp image
limits on the distance scale 1.
For instance, with the lens focused at 0.4 m and an aperture of 11 the image will be sharp within the range
from 0.3 to 0.6 m.
