Claims

[Scope of utility model registration request]

A configuration in which the focal length is switched by inserting and removing an auxiliary lens on the optical axis of the main lens, and at least a part of the finder optical system is switched in conjunction with the switching of the focal length to switch the corresponding angle of view of the finder. In this case, the camera is characterized in that a switch is provided which is operated by a switching operation of a part of the finder optical system, and the contact output of the switch is used as light control F-number switching information for an automatic light control electronic flash.
