Abstract

A camera having a flash, a focal plane shutter, a mechanism for changing a size of a film frame by changing a size of an aperture of the camera, and a mechanism for setting a flash synchronized shutter speed. The focal plane shutter has a leading-shutter-curtain and a trailing-shutter-curtain, which are moved in a vertical direction of the aperture to thereby open and close the aperture. The changing mechanism changes the aperture size in the vertical direction to obtain a panoramic style frame and a standard frame. The setting mechanism sets the flash synchronized shutter speed to a high speed when the aperture is changed to a panoramic style frame having a vertical size which is smaller than that of a standard frame. The output of the flash can be started at a time at which a trailing edge of the leading-shutter-curtain passes a lower side of the panoramic style frame.

A camera including a flash device comprising:

a focal-plane shutter including a leading-shutter-curtain and a trailing-shutter-curtain which are moved in a predetermined direction to open and close a film exposure aperture to thereby expose a film;
means for changing a size of said film aperture to a frame size corresponding to a change in said predetermined direction in which said leading and trailing-shutter-curtains are moved;
means for switching said flash device to cause an output of said flash device;
and
means for controlling said switching means in accordance with a size of said film aperture so that the output of said flash is ended just before said trailing-shutter-curtain starts to close said film aperture.
