Shutter and Aperture Adjustment

Shutter and Aperture Adjustment Shutter and Aperture Adjustment Shutter and Aperture Adjustment
Exposure is adjusted by the shutter speed and the
aperture. The shutter speed controls the exposure time
and the aperture controls the amount of incoming light.
Shutter Speed Dial
Adjust the shutter speed by turning the shutter speed
dial to the desired speed as indicated by the numbers on
top of the dial. The dial cannot be turned between
"2000" and "B". The numbers on the shutter speed dial
correspond to shutter speeds between 1/2000 of a
second and one second counting counterclockwise on
the dial. The "B" position, indicating bulb exposure, is
used when making exposures of more than one second.
Thus, when set at "B", the shutter remains open as long
as the shutter release button is depressed.
Be sure to set the dial at one of the click-stop
positions. At the "B" position, adjust it to the white dot
just below "B".
When it is necessary to make a time exposure, first set
the shutter speed dial at "B", Keep the shutter release
button depressed and turn the time lock lever to "L".
Thus, the shutter will remain open even if the finger is
removed from the button. When the lever is returned to
"A", the shutter closes.
Time exposure is also possible by using a lockable
cable release.
It is possible to perform extended exposures of up to
24
