Variable focus lens device in camera |
摘要 |
An initial position of a variable focus lens is set substantially halfway between a wide and a telephotographing end. Thus, just after the initial position is set by turning on a power switch, both the wide photographing and the telephotographing can be performed quickly. The instantaneous change of a moving object can be quickly photographed in a desired visual field. In the present invention, a composition at the initial position which is set by turning on the power switch is not so different from a composition at the wide photographing side or the telephotographing side. Therefore the user is not confused by any composition during photographing.
