PURPOSE:To transmit accurately object distance information on the basis of the position of a photographic lens to transmit focal length information efficiently by switching a lever means, which rotates a turning member interlocking with an object distance related device, in accordance with the position of a main optical system. CONSTITUTION:In the first state where photographing is performed only by a main optical system 4, a turning lever 41 which operates distance display devices and distance detectors 45-48 related to the object distance or object distance related devices such as an object distance signal output device 54, etc. is turned by an interlocking lever 31 for wide angle and the first interlocking pin 39; and when the main optical system 4 is fed out beyond the closest focusing distance position in the first state, turning of the turning lever 41 is stopped, and an interlocking lever 32 for telephotography and the second interlocking pin 40 turn the turning lever 41 when the main optical system 4 is fed out furthermore. |
