Abstract

A camera has an exposure device for effecting a photographing operation on a film in response to manipulation of a member, and a self-timer for causing the exposure device to effect the photographing operation after the counting of a predetermined time. The self-timer has a first state for causing the exposure device to effect the photographing operation only once and a second state for causing the exposure device to effect the photographing operation plural times. The camera comprises a first display for indicating that the self-timer is in an operable state, a second display for indicating that the exposure device functions plural times in response to the manipulation of the member, independently of the self-timer, and a control device for controlling the first and second displays. The control device is adapted to only activate the first display in the first state of the self-timer and to activate both the first and second display in the second state of the self-timer.

Claims

1. A camera comprising:

a) a photographing optical system;

b) exposure means for effecting an exposure operation for exposure on a film;

c) feeding means for effecting a feeding operation for advancing the film by a frame in response to the completion of said exposure operation;

d) adjusting means for varying the focal length of said photographing optical system; and

e) control means for controlling said exposure means and said feeding means for repeating said exposure operation and said feeding operation, wherein said control means causes said adjusting means to vary the focal length of said photographing optical system during an interval between two successive exposure operations, and wherein said control means comprises self-timer means and an operation member to be manipulated for starting the operation of said self-timer means, and said self-timer means is operated repeatedly in response to a single manipulation of said operation member, and said exposure means and said feeding means are activated each time said self-timer means is operated.

2. A camera according to claim 1, wherein said control means is adapted to cause said adjusting means to shorten the focal length of said photographing optical system during an interval between two successive exposure operations.
