Abstract: A photographing apparatus has a body portion to which a lens portion is mountable and to which an image forming luminous flux is conducted from the lens portion, and the photographing apparatus includes an image pickup device having pixels for image pickup and pixels for focus detection, a storage section that retains information of sensitivity characteristics of the pixels for focus detection, and a control amount calculation section that obtains information about an incident angle and an angular range of the image forming luminous flux from the lens portion and calculates information for focus control based on the obtained information and information read from the storage section. The focus control of high precision is enabled with simple configuration, irrespective of a lens system.
