Abstract
When automatic exposure (AE) for AF is performed, an imaging apparatus sets a fastest speed or a predetermined fixed speed as a diaphragm driving speed to reduce the time to be spent for the AF. On the other hand, when an interchangeable lens in which the diaphragm driving speed can be changed is attached to the imaging apparatus, and AE is performed for moving image recording, the imaging apparatus slows down the diaphragm blade driving speed compared to the speed at the time of AE for AF in consideration of the quality of moving image recording and display.
