Angular attachment for the eyepiece of a rangefinder camera

An angular attachment for fixing to an eyepiece of a rangefinder camera with laterally correct and height-correct representation of a finder image at an altered eyepiece angle, comprising:

• a housing for fixing to the eyepiece of the rangefinder camera;
• an image deflection element comprising a Bauernfeind prism with double reflection in one plane;
• and
• a plane glass sheet arranged with an air clearance before a base area of the Bauernfeind prism;
• wherein
• a first region of the base area of the Bauernfeind prism is disposed downstream of an eyepiece finder, an area opposite to this first region is formed as a reflective area and is inclined with respect to the base area in such a way that a ray entering the first region perpendicularly is reflected onto a second region of the base area at an angle of total reflection, the first region and the second region having a common overlap region, and
• a light exit area of the Bauernfeind prism is inclined relative to the base area in such a way that the totally reflected ray impinges perpendicularly on the light exit area.
