Abstract
The optical apparatus includes an image pickup optical system including a focus lens, a controller controlling movement of the focus lens in an optical axis direction of the image pickup optical system, a shake detector detecting a shake amount of the optical apparatus in the optical axis direction, and a memory storing plural shake amounts sequentially detected by the shake detector. The controller calculates, in response to a start instruction of exposure for the image pickup and before start of the exposure, a predictive value of the shake amount for a time point of the exposure based on the plural shake amounts stored in the memory and including at least one shake amount detected after the start instruction of exposure. The controller moves the focus lens to a position corresponding to the predictive value before the start of the exposure.
