    摘要： A compact optical lens barrel mechanism for relativenonrotational displacement of a series of lens elements forming an optical system is provided. Lens elements can be mounted for selective subdivision into operative lens groups for both focusing and introducing a variable soft focus condition. The barrel mechanism includes a mounting cylinder having appropriate linear alignment elements. A translational cylinder is rotatively journalled within the mounting cylinder. Three lens mounting members can be relatively movable and are designed to each carry a predetermined number of lens elements. The rear lens mounting member can be moved by the translational cylinder to provide a variable amount of spherical aberration to produce a soft focus condition. An exterior focusing ring and a soft focus condition ring can be rotatively mounted relative to the stationary mounting cylinder for linearly moving the respective mounting members.

    摘要： An enlarger lens barrel has a cavity provided with an outwardly directed window and a longitudinal bore defining a light passageway between the cavity and the enlarger light source. A diaphragm aperture adjusting ring is rotatable on the barrel and carries a transparent indicator ring provided with aperture designating characters which are movable with the indicator ring across the window. Housed in the cavity is a transparent light guide member having a cylindrically concave radially extending face confronting the bore and a transversely ribbed inside face including longitudinally and slightly radially spaced transverse faces reflecting light incident thereon from the passageway to the window to longitudinally spread the light incident thereon which is transversely diverged by the concave face. The rings are longitudinally shiftable between increment and continuous adjustment positions.

    摘要： In a zoom camera disclosed, a memory of an auto-zooming program lines is provided in which a relation between the object distance and the image mangification added with an element of the depth of field is set in a predetermined manner according to each kind of photographing mode, and such a focal length of a focusing lens is computed that the image mangification is set to be a predetermined value based on the object distance and a program line of a photographing mode selected by a user, whereby the focusing lens is driven so as to obtain the focal length. Consequently, auto-zoom photographing at a depth of field and an image magnification suitable for each kind of photographing mode can be achieved. Further, a memory of program lines set according to the vertical and horizontal camera attitudes in photographing is provided, and the image mangification can be changed over according to each camera attitude.

    摘要： The present invention relates to a device for measuring object distance or an in-focus position used for a camera in which the object distance of focus adjusting condition are measured in a plurality of distance measuring areas in the photographing scene. The device is so constructed as to judge a main object from weight data in correspondence not only with the object distance of each distance measuring area but with the position thereof in the photographing scene. Further, when there is an object nearer than a predetermined distance, the main object is judged from whether the object has a size larger than a predetermined size in the photographing scene. Furthermore, it is judged from the difference between the object distances of adjacent distance measuring areas whether the objects are the same object.
