PROBLEM TO BE SOLVED: To suppress deterioration of optical performance when correcting optical axis shift. SOLUTION: The shake correction apparatus includes an imaging optical system that includes a correction lens which can move in a direction orthogonal to an optical axis. The shake correction apparatus includes: a detection means that detects shake applied to the shake correction apparatus; a determination means that determines a reference position of the correction lens; and a drive means that drives the correction lens with the reference position serving as a center position, to correct the shake detected by the detection means, wherein the determination means determines the reference position such that the correction lens corrects shift from the optical axis of the center of an imaging element that photoelectrically converts incident light from the imaging optical system, in a range where a condition that a Modulation Transfer Function (MTF) of the imaging optical system, when the correction lens is positioned at the determined reference position, is equal to or larger than a threshold is satisfied.
