A shooting apparatus comprising: a photographing optical system having a variable aperture diaphragm; an imaging section that outputs an image signal; a diaphragm position detection section that detects a diaphragm position; a lens control section that controls movement of a focus lens; a storage section that stores an amount of focal shift corresponding to the diaphragm position; a focus detection section that detects a peak of a contrast value based on the image signal, wherein the lens control section, while moving the focus lens to a focusing position based on a position at which the contrast value indicates the peak, corrects a position of the focus lens to be moved, on the basis of a diaphragm position when the position at which the contrast value indicates the peak is detected, a diaphragm position while moving the focus lens, and the amount of focal shift stored in the storage section.
