It may happen that the photographer must be ready to take a picture at any unexpected
moment. In such cases, the lens should be irised close (for example, to relative
aperture of 1:16), and the distance should be set so that the far limit of depth of field
is "
∞
" (one of the "16" graduations of depth-of-field scale 11 being aligned with mark
"
∞
" of distance scale 10). In this instance, the other identically-marked graduation of
the depth-of-field scale will show the close depth-of-field limit, i.e. the shortest
distance by which the photographer can approach the object photographed to obtain
sharp picturing of the latter.
5. Flash Synchronizer (Fig. 1)
Flash synchronizer contacts 9 are intended for operating the shutter at the moment of
the flash.
When an electronic (multiple-action) flash is used, the plug of the flash unit
connecting wire should be inserted in the connector socket of the synchronizer contact
marked with a lightning symbol. The flash circuit will be closed the moment the
frame window gets fully opened.
Only shutter speeds of l/30th of a second and slower and hand-controlled long time
exposures may be us!ed when employing flash synchronizer to contacts.
When single-action flash bulbs are used, the flash unit connecting wire should be
plugged in the synchronizer contact marked with a silhouette of an electric bulb. The
flash circuit in this case will be closed with a delay required for the flash bulb to gain
the required luminous power.
6. Automatic Releaser (Self-Timing Device)
"The "Zorki-6" is provided with a self-timing device which is used whenever it is
desired that the picture is taken with a delay and without direct operation of the
photographer. Thus, when the photographer is taking his own picture in a group
portrait, he mounts and lays the camera, cocks up the shutter and sets the self-timing
device; then the photographer actuates the delayed-action mechanism, having enough
time to take his place in the group to be photographed.
Setting the Automatic Releaser for Operation
Set up the shutter and move the delayed-action setting lever all the way
counterclockwise.
Then, press the delayed-action release button at the desired moment for the shutter to
be automatically released with a 9 to 15-second delay. Upon the shutter release action,
the delayed-action setting lever returns to its initial position. The shutter can be set up
both with the set and released self-timing device. However, it is recommended first to
set the shutter and the selected shutter speed, and only then to wind up the self-timing
device.
To avoid undue wear of the self-timing device spring, it is advisable to wind it up
only when required; in all other cases it should be kept released. Should the shutter
speed dial be set opposite letter "B", the exposure speed, with the self-timing device
in operation, will be not faster than one second. As this exposure time varies for
different cameras, it is advisable to check it with the aid of a stopwatch.
The self-timing device of the "Zorki-6" camera can be operated together with a flash
unit.
