ABSTRACT:
A light redirecting member moves in concert with an aperture mechanism between a first position to redirect light to a metering sensor and a second position to allow light to pass to an imaging sensor. A motor drives the aperture mechanism to predetermined positions, swinging the associated light redirecting member in and out of an optical path from an imaging optical system to the imaging sensor.
