主权项 1. An optical apparatus comprising: a shake detection unit configured to detect a shake of the apparatus; a first optical correction unit configured to correct an image blur based on the shake detected by said shake detection unit; a second optical correction unit configured to correct an image blur based on the shake detected by said shake detection unit; a zoom detection unit configured to detect whether a zoom lens is performing a zoom operation; a correction amount calculation unit configured to calculate, based on the shake, correction amounts to be corrected by said first optical correction unit and said second optical correction unit; and a control unit configured to change a calculation method of the correction amounts calculated by said correction amount calculation unit according to whether the zoom lens performs the zoom operation or whether the zoom lens stops the zoom operation, wherein said control unit controls said correction amount calculation unit to calculate the correction amounts to be corrected by said first optical correction unit and said second optical correction unit by calculation of separating a frequency of the shake when the zoom operation is stopped, and to calculate the correction amounts to be corrected by said first optical correction unit and said second optical correction unit by proportional calculation based on movable ranges of said first optical correction unit and said second optical correction unit when the zoom operation is performed.
