Other Features
After focusing, the Mirror can be locked up before making
an exposure. This is convenient when the camera is used
at slow shutter speeds and is mounted on a tripod for
telephotography, copy work, etc., since even a very small
amount of vibrations should be eliminated.
Self-timer for delayed shutter release. When activated it
will light a red pilot lamp in the front of the camera for eight
seconds and will blink for two seconds before triggering
the shutter.
Time exposures are made by utilizing the Self-timer and
the “B” shutter setting. A new power saving circuit design
switches the battery off and extends is life.
