Abstract: A display device 70 having an organic luminescent element arranged at an object image-forming position of a finder optical system. Frames are formed by parts 31b, 32b, 33b of the negative electrode formed of non-transparent material, an organic electroluminescent material is laminated thereon on the eyepiece side, and a positive electrode formed of transparent material is superimposed thereon on the eyepiece side. Since the non-transparent negative electrodes 31b, 32b, 33b shield the light, the frames are recognized as black frames. When the periphery is dark, a voltage is applied between the electrodes causing the organic electroluminescent material to luminesce, such that the frame itself becomes brighter in display and is readily visible.

Abstract: In a multifunction camera, an area selector is used both as an operation key in a first selection mode for selecting the focus detection area of the focus detection device, and as an operation key in a second selection mode for selecting the function setting of the camera. A mode selector is provided which is settable at three positions including a local position, wide position, and lock position. The focus detection area selected at the local position is locked when the mode selector is set at the lock position and has been moved from the local position to the lock position, whereas the wide position is locked when the mode selector has been moved from the wide position to the lock position.

Abstract: First, a lens is supplied with a power supply LVDD. Then the state of a chip select signal CSL is input, and the processing waits until chip select signal CSL changes from HIGH.fwdarw.LOW.fwdarw.HIGH, that is, until communication preparation on the lens side is completed. When a microcomputer on the lens side is reset and started, the lens side outputs a communication enable signal and thus the time from mounting of the lens to starting of a communication can be reduced. Thus, a lens-exchangeable camera can be provided capable of starting a BL communication in the shortest time depending on the lens.

Abstract: A single-lens reflex camera comprises a taking lens having a zooming optical system, a finder whose angle of view is determined according to a focal length of the taking lens, and an operation member which is manually operated. In the single-lens reflex camera, the focal length of the taking lens is changed by driving the zooming optical system, and the zooming operation is controlled in response to an operation of the operation member so that the focal length of the taking lens is changed in the wide-angle direction by a predetermined amount. An angle of view corresponding to that which is seen before the focal length is changed is displayed within the finder.

Abstract: When a communication header transmit from the lens side to the body side is input, a reset and start detection signal is checked and if the lens is found to have been reset and started, a body/lens identify signal is communicated to exchange identification signals of each other and the like and resetting of the mechanism is instructed. Thus, malfunction of the lens can be prevented even when the microcomputer for the lens side is reset with the lens mounted on the body.
