Abstract

PURPOSE:To make a titled device convenient for use, by providing a deflecting sliding lens in the front of a photographic lens and sliding the deflecting sliding lens in accordance with movement of a lens system due to an auto-focusing device. CONSTITUTION:A finder 2 is fixed to a camera body 1, and a part of a lens system 4 goes in and out in accordance with turning of a distance regulating ring 3' by a helicoid 3 to regulate the distance. Deflecting sliding lenses 5 and 6 where concave and convex lenses are combined are provided in front of the lens system 4, and respective phases of deflecting and sliding lenses 5 and 6 are parallel planes in the position of the distance regulating ring for an object at the distance of infinity, and the sliding lens 5 is held by a fixed frame 7, and the sliding lens 6 is attached to a frame 8 which is turned around a center 0 of the curvature of the lens 6. This frame 8 is provided with a cam receiving part 9, and the sliding lens 6 is moved by a cam 10 which is moved in accordance with rotation of the distance regulating ring 3'.

The sliding lens and its deflection cancel out the parallax of the finder and eliminate the parallax at the photographing distance. In other words, A at any shooting distance relative to the viewfinder field of view.
The photographing range of the lens system whose distance is adjusted by the F device is made to match by sliding the deflection sliding lens which is linked to the AF device.

インダーとの視差に相当−ノるようにしたものである。At the front of the lens system, there are deflection sliding lenses (5) and (6) similar to those used for correcting finder parallax in conventional cameras, which are combined with concave and convex lenses, and are used for correcting parallax in the viewfinder of conventional cameras. At the position of the ridge adjustment tube ring, the respective phases of the deflection sliding lenses (5) and (6) are placed so that they are dimensionally parallel planes, and the deflection sliding lenses (5) are held by a fixed frame (7). The sliding lens (6) has a center of curvature (
The frame (8) is equipped with a cam receiver (9) that is attached to a distance adjustment ring (9).
The cam (10
) causes the sliding lens (6) to slide and the sliding lens (5) (
When the phase of 6) changes and the whole acts like a small-angle prism, and focus adjustment is performed by a predetermined deflection rotation or forward/backward movement, the unevenness of the movement corresponds to 7. One (or both) of the lenses is moved by an arbitrary interlocking mechanism such as a cam so that the amount of deflection is exactly equal to the parallax with the finder for the distance to the subject.
