摘要： A focus condition detecting system for a cata-dioptric lens wherein it can be judged correctly whether or not detection of a focus condition is possible, and a cata-dioptric lens for use with the focus condition detecting system. The system comprises a focus condition detecting means for detecting a relative displacement between a pair of images of light formed by a pair of optical means from beams of light from a pair of different areas of a plane of an exit pupil of a cata-dioptric lens to detect a focus condition of the lens. Data regarding outer and inner radii of an exit pupil or some other peculiar data are fixedly stored in the lens. The data are successively forwarded to a camera body, and depending upon the data, it is judged whether optically accurate detection of a focus condition is possible from a combination of the optical means and the lens. When the judgment is affirmative, the detecting means is rendered operative. A set of interchangeable lenses which contribute to improvement in function of a body of a camera and also to development of a camera system is also provided.

摘要： An exposure controlling system wherein functional restrictions are little even when a cata-dioptric lens is mounted as an interchangeable lens and also provide an interchangeable lens for such an exposure controlling system. The exposure controlling system comprises means for reading data regarding aperture values of an interchangeable lens from the lens, and a light measuring means. In response to outputs of the two means, a display means displays, when the lens is an ordinary lens, a combination of an aperture value and an exposure time to which the ordinary lens can be controlled to provide an appropriate exposure, and when the lens is a cata-dioptric lens, a fixed aperture value and an exposure time for the fixed aperture value of the cata-dioptric lens which time provides an appropriate exposure. A cata-dioptric lens as the interchangeable lens comprises means for receiving a reading instruction signal from a camera body, and means for successively forwarding data peculiar to the cata-dioptric lens to the body in response to the reading instruction signal. The data include data regarding a fully open aperture value and data regarding a maximum aperture value, and the two values are equal to each other.

摘要： In a focus condition detecting device wherein an object image formed by an objective lens of a camera is re-imaged as first and second images on first and second photocell arrays through a pair of re-imaging lenses, a pair of plano-convex lenses are used as the re-imaging lenses to improve the accuracy of focus condition detection. The device is formed into a module and the plano-convex lenses are formed on a transparent plate supported on a main body of the module. An extremely thin masking member for blocking a part of light rays incident on the plano-convex lenses to form the first and second images is sandwiched between the transparent plate and a surface of the module main body. This arrangement prevents the masking member from rising and/or warping which otherwise causes inconsistency in luminous levels between the first and second images on the first and second photocell arrays. Various examples of the arrangement of the masking member to prevent its rising and/or warping are proposed.

摘要： Brightness of a central area in a scene to be photographed and brightness of a peripheral area around the central area are measured, and the brightnesses of respective areas are outputted as first and second values. When the second value is larger than the first value, the first value is corrected by a value which has no relation with the respective measured values. Consequently, a proper controlling brightness value is provided for controlling the exposure.
