Abstract:
1. A camera having an exposure device for photographing an object image formed via a photographing optical system, said camera comprising: a focus adjusting system which performs a search operation for detecting an in-focus position while moving a focusing lens group; a first switch which causes activation of said focus adjusting system; a second switch which causes activation of said exposure device; and a controller which controls operations of said exposure device, wherein, upon said second switch being operated before completion of said search operation after said focus adjusting system starts to operate, said controller terminates said search operation and activates said exposure device after said focus adjusting system performs said search operation up to a specified focal length position in the case where said second switch is operated before said focusing lens group reaches said specified focal length position, wherein, upon said second switch being operated before completion of said search operation after said focus adjusting system starts to operate, said controller immediately terminates said search operation and activates said exposure device in the case where said second switch is operated after said focusing lens group reaches said specified focal length position, wherein, in the case where said in-focus position is detected by said search operation after completion of said search operation, said focusing lens group is moved to said in-focus position and thereupon said controller activates said exposure device, and wherein, in the case where no in-focus position is detected by said search operation after completion of said search operation, said focusing lens group is moved to said specified focal length position and thereupon said controller activates said exposure device.
