PROBLEM TO BE SOLVED: To execute optimum operation by correcting the change of an image- formation position caused by a subject distance even in the case the image- formation position of a subject within a finder is changed. SOLUTION: This device is constituted of an image-formation changing means 1 provided in a finder optical system for observing a subject image and changing the image-formation state of the subject image, a driving means 2 driving the changing means 1, a switching means 5 selectively switching 1st and 2nd operation by inputting 1st operation designation 3 for making the changing means 1 perform specified operation and 2nd operation designation 4 for making it perform different operation from the 1st operation, an operation designating means 6 designating the operation of the changing means 1, and a driving control means 7 transmitting the operation from the switching means 5 according to the instruction from the designating means 6 to the driving means 2. In such a case, the driving means is driven by the 1st and the 2nd operation previously switched by the switching means according to the instruction from the designating means 6 through the driving control means, and the image-formation state of the subject by the finder optical system is changed by the image- formation changing means. |
