Set the chosen "speed/aperture" values on the camera exposure time knob scale and on the lens diaphragm scale. 
Exposures may be set both with the shutter released and cocked turning knob 16 until the selected number aligns 

with index on the top cover. Settings from 1/ 1000 to 1/60 sec. with the shutter released require somewhat more effort 
than when the shutter is cocked.  

Manual exposure "B" setting should be set turning the knob clockwise only (between shutter speeds 1/ 1000 s and "B" 

the ring is locked). 

Set the diaphragm, turning ring 13 until the selected value aligns with the index on the stationary ring. The scale is 

fixed at all diaphragm values. 

For critical focusing,, use the ground-glass surface, microscreen and wedges, or the distance scale.  Turn the ring 

with scale 15. Focusing can be carried out only with the shutter cocked, when the mirror is in the working position and 
the diaphragm is fully open. 

Depth of field is determined by the distance scale with the aid of additional scale 14. Depth of field can be checked by 

the image of the objects details on the ground-glass surface in the field of vision of the viewfinder, after pressing lever 20 
down to the limit of its travel, then the lens will be closed to the opening set previously. After the lever is released, it will 
automatically return to the initial position and the diaphragm will fully open. 

Depending on the specific conditions, composition can also be carried out by the use of the viewfinder hood. 
 

      

 

 

 

 
To replace the TTL prism viewfinder with the viewfinder hood proceed as follows: 
- turn ring 43 clockwise until it aligns with indexes 42 and 41. Depress button 12, lift the TTL prism viewfinder up; 
- set viewfinder hood 45 on the guide pins (in so doing make certain that it is well secured on the camera). 
Open the viewfinder hood, turning front wall 44 in the direction of the arrow illustrated in the Figure. In its end position 

the front wall of the hood is locked and the side and rear walls are automatically folded down. When lock lever 46 is 
shifted up, viewfinder lens 47 is set to the working position. 

Upon completion of shooting with the aid of the viewfinder hood, press the viewfinder lens wall to the front wall of the 

viewfinder until the indexing lever snaps it in, then fold up the side walls (first left-hand, then right-hand), then the rear 
wall, and holding the latter, return the front wall into the initial position. 

In rapid shooting (such as sports photography) the viewfinder hood can be used as a simple frame viewfinder. Then 

window 48 in the rear wall of the viewfinder hood will serve as one frame and the window in the front wall, closed in the 
non-working position with cover 49, as the other. The cover, when depressed, will turn and lock in the end position. 

In shooting with the frame viewfinder focusing is effected either by the use of lens distance scale 15 or by the ground-

glass through the eyepiece. 

To fold down the frame viewfinder depress the wall of eyepiece lens 47, in this case cover 49 will return to the initial 

position. 

After folding down the frame viewfinder, close the viewfinder hood as explained previously. 
To release the camera shutter, gradually depress release button 4 up to the stop. During this action the lens will be 

stopped down, the mirror automatically rises and the shutter operates. 

In the cameras equipped with the lifting MLU (mirror lock up) system, before pressing on the release button 4 you can 

raise the mirror before releasing the shutter. In order to lift the mirror it is necessary to press button 10. at that time the 
mirror will be lifted upwards, however the shutter is not being released. In order to then make an exposure with the mirror
