发明名称 CAMERA
摘要 PROBLEM TO BE SOLVED: To reduce the number of components and to produce a camera at a low cost, in a camera constituted so that the zooming position of a zoom lens is made to reflect in exposure control by a program diagram. SOLUTION: A leaf switch 3 turned off only when a first group barrel 5 and a second group lens barrel 7 are in wide positions is provided. When the leaf switch 3 is tuned on, that is, the first group barrel 5 and the second group lens barrel 7 are placed except the wide positions, the exposure control is executed by an Ev(exposure value) program diagram when the first group barrel 5 and the second group lens barrel 7 are in tele-positions, for instance. When the leaf switch 3 is turned off, the exposure control is executed by the Ev program diagram when the first group barrel 5 and the second group lens barrel 7 are in the wide positions. Thus, it becomes unnecessary to provide a means for detecting a zoom lens position and the number of parts can be reduced.
