Viewfinder for camera

摘要

This invention provides a viewfinder which is mounted separately from a taking lens on a camera and wherein the occupying space of a parallax-correcting prism is minimized to arrange freely its optical design. And also, this invention provides a viewfinder decreasing the difference of the diopter and the fuzziness of the image between normal photographing mode and macro photographing mode. To achieve these objects, this viewfinder comprises a prism arranged in the optical path of said viewfinder to correct the parallax, and a driving mechanism to slide said prism in the direction normal to the axis of said lens system.
