Abstract
The dual-focus change-over camera provides a camera which allows telescope or wide angle photographing with a simple arrangement, and which is inexpensive, small size, and light weighted. The camera comprises a finder change-over member arranged to be movable for establishing two finder openings for different focal distance, a telescope lens and a standard lens for performing photographing with two focal distance, a fixed mirror for reflecting image light from the telescope lens, and a movable mirror movable between a first position (telescope position) for directing the image light from reflected by the fixed mirror to a film and a second position (standard position) for directing the image light from the other standard lens to the film. Then, the movable mirror is rotated to the first or second position in interlocking with the sliding operation of the finder change-over member. Thus, dual-focus photographing such as telescoping and standard photographing, or standard and closed photographing can be attained with a simple arrangement.
