ABSTRACT:
In the disclosed device, a timer delays operation of a focus control until sufficient time has elapsed for a range finder to measure the distance to an object. According to an embodiment, depressing the shutter button to a first position actuates the range finder and, depressing it to a second position, actuates a focus control. A timer prevents actuation of the focus control if the shutter button is depressed to the second position before the time allotted for the operation of the range finder has elapsed.
