1. An optical apparatus comprising:
- a shake detection unit configured to detect shaking of the optical apparatus;
an image blur correction lens;
a correction unit configured to drive the image blur correction lens on the basis of a result of the detection performed by the shake detection unit and configured to correct image blur caused by the shaking;
a position detection unit configured to detect a position of the image blur correction lens; and
a selection unit configured to allow selection of whether performance of image blur correction by the correction unit is to be permitted or inhibited,wherein the optical apparatus includes a camera capable of capturing an object image, andwherein if image blur correction is permitted, the correction unit drives the image blur correction lens on the basis of an output from the shake detection unit, in accordance with a first driving characteristic which exhibits a first frequency characteristic, and if image blur correction is inhibited, the correction unit holds the image blur correction lens at a position aligned with an optical axis of the optical apparatus on the basis of an output from the position detection unit, in accordance with a second driving characteristic, which exhibits a second frequency characteristic that is different from the first frequency characteristic.

Abstract
An optical apparatus includes a shake detection unit to detect shaking applied to a camera; an image blur correction driving unit for driving a lens and correcting image blur caused by the shaking; and a selection unit configured to select whether correction of image blur is to be permitted or inhibited. If image blur correction is permitted, the image blur correction driving unit operates in accordance with a first driving characteristic. If image blur correction is inhibited, the image blur correction driving unit holds the lens near an optical axis in accordance with a second driving characteristic.
