PURPOSE:To prevent a deterioration in an image caused by the fact that the influence of aberration becomes great because a focal distance is made long by providing a control means for making the actuating range of an image shake preventing means small. CONSTITUTION:The control means for making the actuating range of the image shake preventing means for preventing the shake of the image due to movement in an optical path because the focal length is made long is provided to prevent the influence of the aberration on the image from being too great. In other words, a focal length sensor 1 detects the position of the variator lens of a zoom lens 52 or the like. Moreover, maximum shake angle data 2 is stored in a microcomputer 46 as a table corresponding to the focal length. Then, the information of the focal length is fetched in the microcomputer 46 for controlling a variable apex angle to prevent the shake and the maximum shake angle in use of a variable apex angle prism 41 used is regulated from the result of the detection. |
