Abstract

PURPOSE:To photograph an in-focus picture merely through release operation, by loading and holding automatically an attachment lens for short-distance photography on the front surface of a photographic lens. CONSTITUTION:The pin 8 of a locking lever 4 is at the highest point (c) of the cam surface of a cam gear 10 and the attachment lens 6 is loaded on the front surface of the photographic lens 3. In this state, when a distance measuring mechanism outputs a short-distance measurement signal, a holding mechanism 12 holds the lever 4. Namely, a shutter is released in the state wherein the lens 6 is mounted on the front surface of the photographic lens 3. When the short- distance measurement signal is not outputted, the holding mechanism 12 does not operate and the pin 8 of the lever 4 reaches a point (d) in a lower surface as a cam gear 10 rotates, releasing the shutter. Namely, the lens 6 moves away from the front surface of the photographic lens 3 except in the short-distance photography.

The Nonomera, which uses a fixed focal length lens as the 4th shadow lens, is well known, and since there is no need for focusing within the depth of focus of such a Canora d-photographing lens, the original intention of the camera was to take instantaneous n++ shots. While this has the advantage of matching, it also has the inconvenience of not being able to take pictures within the close range, which is outside the focal point 7 depth of the lens. Therefore, recent cameras
A model C has also appeared in which an attachment lens for close-up photography can be inserted into the front of the fixed focus lens.
