PROBLEM TO BE SOLVED: To surely prevent the occurrence of the camera-shake not planned by a photographer in a photographed image of a camera having a zoom lens. SOLUTION: When a set shutter speed is lower than a camera-shake threshold speed at that time, there is a probability of occurrence for camera-shake, and therefore the macrozoom lens 301 is moved to a wide side up to the focal length at which the camera-shake will not occur. When the set shutter speed is higher than the camera-shake threshold speed at that time, a switch Z2 is operated by an operator and when the macrozoom lens 301 is attempted to be moved to a telephoto side, a zoom controls section 2115 moves the macrozoom lens 301 to the telephoto side, but when the focal length (zoom ratio) becomes the focal length on the camera-shake threshold line L, the movement of the macrozoom lens 301 is forcibly stopped. |
