EXPOSURE SETTING
A gentle upward pull on the shutter speed dial followed by a rotating movement sets the shutter speed duration.
The selected speed figure is aligned with the index mark in the middle of the dial, then depressed to fix it in the
primed position. Figures indicated are in fractions of a second. 'B' indicates a hand-controlled exposure
duration.

Time exposures are obtained by first cocking the shutter: setting the dial to 'B'; then, by pressing the release
button until locked by rotating it .
It is released by turning the release button to its former position.
NOTE:
1. The exposure duration can be set both with the shutter cocked and released.
2. Use a tripod for slow shutter speeds on 'bulb' exposure.
3. When photographing without flash bulbs the synchro setting lever can be set at X.
STOP SETTING
To set apertures on the 58mm HELIOS lens: set the index mark to align the selected aperture figure engraved
on the aperture-setting ring of the lens. Each setting is click-stopped at each aperture setting. The same
procedure applies to the INDUSTAR-50 lens except that with this lens there are no click stops: the lens aperture
is set only after focusing.
