SHUTTER RELEASE OPERATION
For sharp pictures, correct shutter releasing is just as im­
portant as steady camera holding. After advancing the
film to a fresh frame, the camera is set for shutter release
via the button provided at the upper right. When taking
the picture, hold the camera steady (as explained pre­
viously), relax and depress the button using a steady
even pressure to release the camera’s shutter-remember,
a quick jab of the finger will cause camera movement
and may result in a blurred photograph.
Operation via Cable Release
The shutter-release button can also be operated via a
cable release or similar accessory attached via the thread­
ed mount provided. With the cable release, operation is
more vibration-free and often leads to sharper images
under critical shooting situations such as photomicro­
graphy, time exposure, etc. To attach the cable release
(Nikon-mount models AR-2, etc.) to the camera, screw
the threaded cable connector onto the mount provided
around the button. The shutter is then tripped by de­
pressing the release plunger.
