To prevent a user from failing in photographing all the more because he(she) puts too much confidence in a vibration-proof system and to enable him(her) to execute the photographing with appropriate exposure.

This focal distance variable camera provided with the vibration- proof system for restraining shake and an exposure time calculation means calculating an exposure time at the time of photographing is provided with an exposure control means controlling so that exposure may be performed in a state where the exposure time is fixed to specified shutter closing time when the calculated exposure time is longer than the specified shutter closing time, and a photographing condition change means (#1007 to #1017) changing the specified shutter closing time according as the vibration-proof system is used or not and according to the focal distance at the time of photographing.
