Abstract: An angular attachment has a housing (1) for fixing to an eyepiece (15) of a rangefinder camera (21) with laterally correct and height-correct representation of the finder image at an altered eyepiece angle, which contains a Bauernfeind prism (5) with double reflection in one plane as an image deflection element, a first region (A, A?) of a base area (4) of the Bauernfeind prism (5) is disposed downstream of the eyepiece finder (15), an area opposite to this region is formed as a reflective area (8) and is inclined with respect to the base area (4) in such a way that a ray (2) entering the first region perpendicularly is reflected onto a second region (B, B?) of the base area (4) at an angle of total reflection, and a light exit area (10) of the Bauernfeind prism (5) is inclined relative to the base area (4) in such a way that the totally reflected ray (9) impinges perpendicularly on the light exit area (10).

Abstract: An optical lens arrangement for a rangefinder system in a photographic camera with a fixed viewfinder magnification SK and a fixed measuring base MB is configured to be coupled with a rangefinder eyepiece of the rangefinder system and is designed as an afocal telescope with a minimum 1.1 times and a maximum 1.7 times magnification SL. The magnification SL may be selected so that the product of the viewfinder magnification SK and the magnification SL is at least very nearly equal to 1.
