ABSTRACT:
This zooming device performs auto-zooming by determining the focal length based on the object distance. When the degree of zooming is large, it performs zooming at a speed appropriate to that degree. Further, when a conversion lens is mounted to change the focal length, the device determines focal length while taking into account the degree of change in focal length effected by the conversion lens.
