6. Self-timer, synchro socket, lens changing, operating the self-timer
6.1. Operating with self-timer
To use the self-timer mount the camera on a tripod. Then do the following:
a)focus the lens;
b)set the exposure;
c)cock the shutter;
d)wind the self-timer mechanism by turning lever 1 downwards as far as it will go;
e)change diaphragm selector switch 28 from “A” (Automatic) to “M” (Manual) position;
f)press self-timer release button 2 and take your place in front of the lens. The shutter will operate in no less than 7 seconds after pressing the button.
6.2. Taking flash pictures
The camera shutter is synchronized for use with different types of electronic flashes (X-synchronization). Before taking flash pictures remove protective strip 12. To connect an electronic flash with the camera, the latter is provided with socket 4 located on the front wall of the camera. The camera design provides as well for cableless connection of electronic flashes. The shutter speed of 1/30 s. only can be used for flash photography.
6.3. Using interchangeable lenses and taking pictures at close distance
The camera accepts interchangeable lenses provided with M42x1 mounting thread and flange/film distance of 45,5 mm.
If an interchangeable lens has no automatic diaphragm mechanism, the diaphragm can be handled manually. When long focus lenses are used, a slight cutting
of the left or right edges of the image on negative is likely to take place. With the help of a special stand the ZENIT-TTL camera can be used for making reproductions of drawings, manuscripts, photographs. When making reproduction works, use should be made of extension tubes by setting them between the camera body and the lens. To obtain a necessary scale either one tube or a combination of some tubes can be used.
The extension tubes without pushers being used, the lens diaphragm should be operated manually and the diaphragm mode selector switch should be set to “M” mode.
6.4. Changing the power source if exposure meter electric circuit
To change a Mallory PX-13 battery do the following: turn cap 15 in the counter-clockwise direction as far as it will go without applying excessive effort and take out the exhausted battery; Put a new one into the compartment with sign “ + ” outwards. Cap the compartment. In the closed position of the cap its slot should be placed vertically.
