Time Exposures - Konica AUTOREFLEX T3 Mode D'emploi

TIME EXPOSURE
If the shutter speed dial is set to "B", the shutter will be
open as long as the shutter release button is pressed down.
This method is usable for more than one second of exposure.
When such a long time exposure is required, turn the Shutter
Lock Control (3) and set it to "OFF" while the shutter
release button is kept depressed. In this way, the film will be
exposed even if your finger is detached from the button.
When the shutter lock control is returned to "ON", the
shutter will be closed and the film will no longer be exposed.

• The AEC system is unusable for time exposure. Set your
camera to manual for aperture determination.
• To prevent your camera from being accidentally jarred, it
is necessary to prepare a tripod and cable release. The
KONICA Cable Release 3 with a lock has a "T" stopper,
so that it may be put to use for time exposure without a
releast lock lever.
NOTE: Don't turn the shutter speed dial during time
exposure. Nor must it be turned while the self-timer is in
operation.
