Abstract
An apparatus includes a control unit configured to control an aperture diameter of a diaphragm based on a result of photometry, a determination unit that, in a case where t light flux enters the imaging unit via a predetermined optical member which has light transmitted in quantities varying stepwise in a radial direction with respect to and optical axis, determine whether there exists a plurality of F numbers that indicates the aperture diameter of the diaphragm at which approximately identical quantities of light enter the imaging unit. In a case where the determination unit determines that there exists a plurality of F numbers at which approximately identical quantities of light enter the imaging unit, the control unit controls the F number to be differently set in accordance with information regarding an image capturing condition.
