ABSTRACT:
A camera system which is capable of performing highly accurate focusing in a short time by using two kinds of AF methods, is disclosed. The camera system calculates the target driving amount of the focusing lens based on the result of detection by a first focus detection unit, and performs a first driving control to drive the focusing lens toward a position corresponding to the target driving amount and a second driving control to drive the focusing lens based on the result of detection by the second focus detection unit. When the remaining driving amount to the target driving amount of the focusing lens by the first driving control becomes a predetermined amount, the camera system switches from the first driving control to the second driving control without stopping the focusing lens.
