Title:
FINDER DEVICE
Document Type and Number:
Japanese Patent JP2002372737
Kind Code:
A
Abstract:

To correct parallax by a see-through type finder device and to confirm a focusing state at close-up-photographing.

A close-up lens 13 is integrally arranged with a lens holder 53 which is arranged so as to be freely rotated in a plane vertical to a photographing optical axis. As a macro lens 5 supported by the lens holder 53 is inserted in front of an exposure aperture 58, the close-up lens 13 is inserted inside a finder window 66. The central part of the close-up finder visual field 70 is visually enlarged by the close-up lens 13, then, in the case of framing an object through the close-up lens 13, the compositional arrangement where the object is arranged at nearly the center of a photographic picture frame is obtained, then, the parallax of the finder 12 is corrected. In the case of viewing the object through the close-up lens, 13, the object is clearly viewed at the focal distance of the macro lens 5, but, the object is not clearly viewed at the distance before and behind the focal distance, consequently, the focusing state at close-up-photographing is confirmed.
