ABSTRACT:
An imaging apparatus includes an imaging unit configured to photoelectrically convert light of an object image formed by an imaging optical system to generate a signal, a first detection unit configured to detect a focusing state of the imaging optical system based on the signal generated by the imaging unit, a sensor configured to generate a signal different from the signal generated by the imaging unit without using the imaging optical system, and a second detection unit configured to detect an in-focus position of the imaging optical system based on the signal generated by the sensor. The sensor is located such that an amount of overlap between a detection range of the first detection unit and a detection range of the second detection unit at a first object distance is equal to an amount of overlap between those at a second object distance that is close to an infinite distance side compared to the first object distance.
