Shooting apparatus including a diaphragm

A camera system including an interchangeable lens with a photographing optical system having a variable aperture diaphragm, and a camera body to and from which the interchangeable lens is attachable and detachable, the camera system comprising:

• in the interchangeable lens,
• a diaphragm position detection section that detects a diaphragm position corresponding to the aperture diaphragm in the photographing optical system;
• a lens control section that controls movement of a focus lens included in the photographing optical system;
• and
• a storage section that stores an amount of focal shift in the photographing optical system corresponding to the diaphragm position, and
• in the camera body:
• a main body control section that communicates with the lens control section;
• and
• a diaphragm position storage section that stores the diaphragm position sent by the lens control section and received by the main body control section, wherein
• the main body control section sends the stored diaphragm position stored in the diaphragm position storage section and a target position to which the focus lens is moved, to the lens control section, and
• the lens control section, while moving the focus lens to the target position, corrects the target position of the focus lens to be moved, on the basis of the stored diaphragm position, a diaphragm position while moving the focus lens, and the amount of focal shift stored in the storage section.
