Abstract

A lens apparatus includes a detector configured to detect a camera shake, a correction unit configured to correct an image shake caused by the camera shake based on the detected camera shake, a driving device configured to move the correction unit, a holder holding the detector, and a fiber assembly via which the holder holds the detector.

First claim

What is claimed is:

1. A lens apparatus comprising:
a detector configured to detect a camera shake;
a correction unit configured to correct an image shake caused by the camera shake based on the detected camera shake;
a driving device configured to move the correction unit; and
a holder holding the detector,
wherein the detector is held indirectly by the holder such that a flexible printed substrate to which the detector is connected and a fiber assembly formed of a felt or a non-woven fabric are interposed between the detector and the holder.

2. The apparatus according to claim 1 ,
wherein the correction unit includes a lens configured to move in a direction orthogonal to an optical axis of the apparatus.

3. The apparatus according to claim 1 , further comprising a mass addition member arranged with the detector.

4. The apparatus according to claim 1 , wherein fibers of the fiber assembly are intertwined with each other in three dimensions.

5. The apparatus according to claim 1 ,
wherein the correction unit includes an image pickup element.

6. The apparatus according to claim 1 , wherein the holder is a casing in the apparatus.

7. The apparatus according to claim 1 , wherein the holder comprises a fixed barrel of the apparatus.

8. A camera system comprising:
a lens apparatus;
an image pickup apparatus including an image pickup element and a casing holding the image pickup element;
a detector configured to detect a camera shake;
a correction unit configured to correct an image shake caused by the camera shake based on the detected camera shake;
a driving device configured to move the correction unit; and
a holder holding the detector,
wherein the detector is held indirectly by the holder such that a flexible printed substrate to which the detector is connected and a fiber assembly formed of a felt or a non-woven fabric are interposed between the detector and the holder.

9. The camera system according to claim 8 ,
wherein the correction unit includes a lens configured to move in a direction orthogonal to an optical axis of the lens apparatus.

10. The camera system according to claim 8 , further comprising a mass addition member arranged with the detector.

11. The camera system according to claim 8 , wherein fibers of the fiber assembly are intertwined with each other in three dimensions.

12. The camera system according to claim 8 , wherein the holder is a casing in the image pickup apparatus.

13. The camera system according to claim 8 , wherein the holder comprises a fixed barrel of the lens apparatus.
