摘要:
A camera having a photo-taking lens changeable over to two different focal lengths includes display means for displaying a scale indicative of distances, the scale being displayed by the display means so as to be along a predetermined surface, the scale having a plurality of symbols, means for producing a first detection signal when the focal length of the photo-taking lens is one of the two different focal lengths and producing a second detection signal when the focal length of the photo-taking lens is the other of the two different focal lengths, and control means for controlling the display means, the control means being responsive to the first detection signal to control the display means so that a part of the plurality of symbols is displayed and being responsive to the second detection signal to control the display means so that the remainder of the plurality of symbols except said part is displayed.
