摘要：
A shutter control apparatus for use with a variable focal length camera which has a lens shutter, a detecting means for detecting a fully opened state of the lens shutter, a discriminating means for discriminating the focal length of a photographing optical system, and a controlling means for closing the lens shutter in response to the detection of the fully opened state of the lens shutter made by the detecting means when the discriminating means determined that the photographing optical system has a longer focal length during flash photography.
