in manual mode one can estimate the image sharpness within the ground glass circle without pressing the release button.

4.5. Exposure setting with the aid of the exposure meter

Semi-automatic exposure meter of your camera measures the light getting into the camera through the lens (TTL system). As a result you can set the exposure with the high degree of accuracy depending upon the brightness of the subject and the speed of photographic material by varying the shutter speed and aperture value.

The system operates as well with interchangeable

lenses, light filters, supplementary lenses and extension tubes. Turn the film speed setting dial and set the speed value of the film loaded in the camera against the index mark on the camera shield. Set the diaphragm mode selector switch in “A” mode.

Watching in the viewfinder eyepiece in such a way that the whole of its frame would be clearly seen, press release button 3 till a definite stop but not till the shutter operation, should it be cocked.

With the release button depressed, the exposure is excessive if the needle deflects from the index mark to sign “+” and insufficient if it deflects to sign “–”.

Keep the release button depressed and turn diaphragm setting ring 27 or shutter speed dial 8 till you match the needle with the index mark. Should you fail to match the needle with the index mark with all possible combinations of diaphragm and shutter speed values, you should either change the subject illumination or use a film of a different speed.

5. Picture taking

5.1. Picture taking

Having prepared the camera for picture taking, cock the shutter, make sure of correct focusing and exposure setting, and smoothly press release button 3 to take a picture.

Remember, that sharp pressure on the release button results in the camera shaking at the moment of exposure and thus in blurring of the picture.

5.2. Unloading the camera

When the exposure counter dial shows 36 shots, rewind the exposed film into the cassette. To do this:

a)disengage the shutter by turning shutter disengaging bush 9 as far as it will go in the direction of the arrow on the camera shield;

b)lift crank 6 and rotate the film rewind knob in the arrow direction until the film leaves the take-up spool;

c)pull out the film rewind knob as far as it will go, open the back door, and take the cassette out of the camera;

d)turn the shutter disengaging bush clockwise to return it into the initial position.
