Abstract

The invention relates to a method for producing a photographic lens (11) which comprises a translucent main part (12) and optical imaging elements (3a-h) arranged along a folded optical axis OA. The angle α between sections of the optical axis OA1 - OA9 is less than 180 degrees in front of and behind the fold. The optical imaging elements (3a-h) comprise reflective elements, at least one of which has a reflective surface curved in a non-rotationally symmetrical manner. The production method has the steps of producing a translucent main part (12) and forming the optical imaging elements (3a-h) in the main part (12). The invention additionally relates to a method for producing an image capturing device (10), to a photographic lens (11), and to an image capturing device (10).
