摘要： In an interchangeable lens including an optical system adjustable for focusing and adapted to be detachably mounted on a camera body which is provided with focus detection means for detecting an amount of defocus of an object image formed by the optical system, and drive means for driving the optical system for the focus adjustment thereof in accordance with the detected amount of defocus. The interchangeable lens comprises, inter alia, a code plate for producing a plurality of digital photographic distance signals representing given discrete photographic distances of the optical system in accordance with the adjustment of the optical system for focusing. Circuit means output a predetermined one of a plurality of inputs, the plurality of outputs including a plurality of conversion coefficients needed for converting the detected amount of defocus into the amount of drive to be effected by the driving means, the conversion coefficients being intrinsic to the interchangeable lens and having values depending upon the discrete photographic distances of the optical system represented by the digital photographic distance signals, respectively.The digital photographic distance signals are applied to the circuit means as the predetermined input to cause the circuit means to output one of the conversion coefficients as the predetermined output, the value of which depends upon the photographic distance of the optical system represented by the one digital photographic distance signal being produced. The output conversion coefficient are transmitted to the camera body.

摘要： A winding and rewinding apparatus for a camera comprises a winding mechanism, a detector, a rewinding mechanism, a selector and a controller. The winding mechanism winds the film frame by frame, and the detector detects the completion of exposure of the roll of film which is wound by the winding mechanism. The rewinding mechanism rewinds the film automatically in response to the detection of the detecting means. The selector includes a selecting switch which is operable manually, for selecting in response to the operation of the selecting switch one of a first mode in which the operation of the rewinding mechanism is permitted and a second mode in which the operation of the rewinding mechanism is inhibited irrespective of the detection of the detector. The controller controls the rewinding mechanism in accordance with the mode selected by the selecting switch. According to such arrangement, the user can select a manual rewinding mode or an automatic rewinding mode by a simple operation.

摘要： A lighting device such as an electronic flash device attachable to a camera body includes first and second light projecting optical systems which project first and second light fluxes for illuminating an object to aid focus detection by a focus detection device. The second light flux spreads at a larger solid angle than the first light flux and illuminates a first distance zone which extends to a closer distance side while covering the whole of a second distance zone illuminated by the first light flux. An optical wedge disposed in the second light projecting optical system deflects a part of the second light flux towards the closer distance side of the first distance zone. Another lighting device includes a single light projecting optical system but it also includes an optical wedge for deflecting a part of a light flux projected by the light projecting optical system to widen a distance zone illuminated by the light flux towards a closer distance. The optical wedge also serves to produce a difference in intensity distribution of the light flux such that the light flux has higher intensity at a part thereof for illuminating a farther distance side of the distance zone than at a part thereof for illuminating a closer distance side of the distance zone. A light source of the light projecting optical system(s) is provided with a conical light reflecter surrounding a light emitting diode to reflect light emitted from side surfaces of the light emitting diode forward.

摘要： A pentagonal prism for use in a viewfinder of a single lens reflex camera makes use of total reflection of viewfinder light flux at effective optical path regions on its pair of roof surfaces. The prism constitutes a module together with a protection cover attachable thereto for protection of the roof surfaces. The cover is provided with a pair of roof walls accomodated to the roof surfaces of the prism and including recessed portions corresponding to the effective optical path regions on the roof surfaces and peripheral portions corresponding to portions on the roof walls out of the effective optical path regions. Upon attachment of the cover to the prism, the peripheral portions contact the portions on the roof surfaces out of the effective optical path regions and an air space which ensures the total reflection is left between the inner surfaces of the recessed portions and the effective optical path regions on the roof surfaces. A ghost may be prevented from occurring when the inner surfaces of the roof walls are black-frosted, black-ground or black-roughened for light absorption or when the roof walls are designed to intersect with one another at a ridge angle of less than 90.degree. .

摘要： A camera system with an auto-focusing system includes a camera body and an interchangeable zoom lens. The interchangeable objective lens stores various data to be sent to the camera body for improving automatic focus adjustment, such as an information necessary to convert the detected defocus information into a movement of the driving power source to carry out the automatic focus adjustment. The driving power source in the camera body is controlled in responses to the data from the interchangeable objective lens and the detected focus information, the driving power being transmitted to the interchangeable objective lens. The camera body is further capable of inhibiting the focus adjustment or focus indication in response to a data from the interchangeable objective lens under an unfavorable condition.
