Patent ID: 8866917

Claim:
An optical apparatus comprising: a compensation lens configured to compensate for a blur in an image formed by an imaging optical system by moving in a first direction different from an optical axis; a shake detector configured to detect a shake of the apparatus; a position detector configured to detect a position of said compensation lens in the first direction; a calculator configured to calculate a drive target position of said compensation lens based on a shake amount that is output from said shake detector and the position of said compensation lens; a driver configured to drive said compensation lens to the drive target position; and a position controller configured to make a positional resolution of said compensation lens in the first direction in still image capturing be higher than a positional resolution of said compensation lens in the first direction in moving image capturing, wherein in moving image capturing, said position controller makes the positional resolution of said compensation lens in the first direction when the shake amount is equal to or less than a predetermined value be higher than the positional resolution of said compensation lens in the first direction when the shake amount is greater than the predetermined value.
