ABSTRACT:
A display system for a camera which can make a display of a focal length of the camera on an existing display device for display of a photographing frame count of a film without provision of an additional display device and without increasing the number of display segments of the existing display device. The display system comprises a display means, a first display control means for controlling the display means to display a frame count of a film, a taking lens having a variable focal length, a detecting means for detecting a focal length of the taking lens, a second display control means for controlling the display means to display the focal length of the taking lens detected by the detecting means, and a changing means for alternatively rendering the first or second display control means effective. The display means thus normally displays a current frame count of a film in the camera but displays a current focal length of the taking lens, for example, when the focal length of the taking lens is being varied.
