ABSTRACT:
An auto-focus camera for performing focusing adjustment of a focusing lens group to actualize an in-focus state, that includes an auto-focusing adjustment unit to move the focusing lens group along an optical axis based on a detection signal, and an in-focus state detection unit to detect the in-focus state and output a corresponding output signal. The auto-focusing adjustment unit performs the focus adjustment using the output signal of the in-focus state detection unit as the detection signal. The auto-focus camera also includes a displacement detection unit to detect displacement of the photographic optical system along the optical axis and to output a corresponding output signal. The auto-focusing adjustment unit switches the detection signal from the output signal of the in-focus state detection unit to the output signal of the displacement detection unit to enable continued focusing adjustment throughout the photographic operation, including during an exposure process.
