A vehicular headlight, in particular an automobile headlight, including a reflector (1) having a reflecting surface, is capable of illuminating a flat target surface to be illuminated with a desired light distribution by optimal utilization of the light source of the headlight. Therefore the optically effective surface of the headlight is characterized by point asymmetry in substantially all planes cutting said reflecting surface. This can be realized by using a method for producing said optical surface comprising the steps of:

A viewfinder for a camera includes a near-subject frame visible in the finder field to frame subjects closer to the camera than a predetermined distance, e.g., four feet, and a normal frame visible in the finder field to frame subjects beyond that distance. The near-subject frame defines a subject-field that is offset from the subject-field defined by the normal frame to correct for the parallax error at close distances. A focus-setting device for the camera lens has a near-subject setting for close-up subjects and a distant-subject setting for other subjects. When the focus-setting device is set to its distant-subject setting, for use with the normal frame, the near-subject frame is not visible. This prevents the near-subject frame from being confused with the normal frame. The near-subject frame is only made visible in response to the focus-setting device being set to its near-subject setting. Making the near-subject frame visible alerts the photographer to use that frame instead of the normal frame.

Camera viewfinder

A viewfinder of the inverted Galilean type, for use with a photographic camera having a pair of interchangeable objective lenses, comprising a viewfinder lens, an eyepiece having two reticles formed thereon, a fixed mirror frame and a movable mirror frame. The fixed mirror produces a projected virtual image of one reticle. Structure is provided for positioning the movable mirror to produce a projected virtual image of the second reticle in response to interchange of the objective lenses.
