Description

ABSTRACT:
An exposure delay mechanism is initially actuatable to release the reflex mirror of a reflex camera to its film exposing position and to block movement of the shutter. The operator may wait for any desired time interval before actuating the exposure delay mechanism to release the camera operating mechanism to operate the shutter and expose the film. In this manner, the operator may wait until after shock vibrations caused by movement of the reflex mirror have subsided and for any other desired interval before exposing the film. The delay mechanism utilizes a member such as a flexible cable which is movable selectively into and out of the path of movement of a component of the camera operating mechanism which is operative to open the camera shutter after movement of the reflex mirror.
