    摘要: An auto-focusing system includes a focus condition detector which detects the focus condition based on infrared light. A data producer is provided for producing a deflection signal indicating the difference between an image forming distance for infrared light and that for visible light, due to aberration. In accordance with the detected focus condition and deflection signal, an objective lens is shifted to a position for properly focusing an image of visible light on an image forming plane.

    摘要: A film transporting device for use in a camera disclosed is so designed as to rewind the film such that no film portion is engaged in film take-up sprocket, resulting in an easy take out of the use film. The device in one form includes a counter that counts up the number of frames during a wind-up operation is carried out after the positioning of a film leader in contact with the take-up sprocket, and during a rewind operation, the counter counts down the same number of frames, or more, to locate the film leader in a disengaged position from the sprocket. The device in another form includes a film perforation detector. In this form, the film rewind operation is carried out until the perforation detector stops detecting the perforation. In a further form, the device includes a mechanical counter which counts up the frames used during wind-up operation, and during rewind operation counts down more than the number counted up to ensure that the film leader portion is withdrawn from the take-up sprocket.

    摘要: A camera system having an interchangeable objective lens selectively mountable to at least two different types of camera bodies of a, first type and second type, is involved. The camera system has a ROM located in the interchangeable objective lens for storing a plurality of compensation data: one is suitable for the first type camera body; and the other is suitable for the second type camera body. Each data compensates an error in fully-open aperture light measurement for each type of camera. The compensation data is transmitted from the lens to the camera body. A register is provided in the camera body for storing a selected compensation data which is necessary for the type of camera body mounted with the lens. A device is provided in the camera body for practicing a fully-open aperture light measurement through the interchangeable objective lens to produce a light measuring information including the light measurement error. A calculator is provided in the camera body for calculating a correct exposure information using the compensation data stored in the register and the light measuring signal, whereby the error included in the light measuring signal can be removed.

    摘要: A camera in which the ratio of an object to the photographing frame can be set comprises a varifocal lens in which the in-focus position is changed in accordance with the change in the focal lens and a focusing lens for correcting the focus by the varifocal lens. The size of the object is set to the desired size by using the varifocal lens, and thereafter the deviation of the in-focus point is controlled by the focusing lens. Since the zooming is carried out by using a varifocal lens, a camera can be provided in which the ratio of an object to the photographing frame can be set in a simple structure.
