<P>PROBLEM TO BE SOLVED: To realize excellent soft focus photography even in the case of a simple photographic lens. <P>SOLUTION: The photographic lens of f32 mm is used and a focal position is set to 6 m. When a subject distance is set to about 3 m and release operation is performed, a kicking lever 60 normally rotates a turning lever 51, and a shutter driving lever 52 is rocked counterclockwise. A driving pin 52a engaged in cam holes 53c and 54c is displaced so that shutter blades 53 and 54 start to open. A middle part between the holes 53c and 54c has shape along the orbit of the pin 52a, and a small diaphragm aperture 55 set at F11 is maintained for about 3 to 4 msec in the midst of opening the blades 53 and 54. During such operation, a synchronization switch 37 is turned on so as to emit strobe light, and a sharp image is exposed. Thereafter, an aperture for exposure 48a is totally opened and the open diaphragm set at F5.6 is maintained for about 1/60 seconds, and a somewhat blurred image is exposed, then the blades 53 and are closed. <P>COPYRIGHT: (C)2003,JPO |
