Abstract
It is an object of the present invention to provide a finder prism capable of forming some in-finder information such as an automatic focus target mark and a short distance correction mark by virtue of extremely narrow lines. In detail, the finder prism is provided between an objective lens and an ocular lens, and is adapted to transmit an object image to a camera user under a condition where an automatic focus target mark and an short distance correction mark are overlapped on a photographing object image. In particular, the prism is made of a resin, a shouldered portion is formed on one surface of the prism from which the object light is allowed to exit during a photographing process, thereby forming some in-finder information such as an automatic focus target mark and an short distance correction mark.
