Abstract
An additional optical element with a positive optical power is used to influence an optical image produced by the camera lens on the image sensor by inserting the additional optical element between a camera lens and an image sensor of a camera, wherein the center thickness of the additional optical element and the optical power of the additional optical element are matched to one another in such a way that, for a predetermined diaphragm setting of the camera lens, a flange focal distance defined by the camera lens remains substantially unchanged by the insertion of the additional optical element.

Use of an additional optical element with a positive optical power for influencing an optical image produced by a camera lens on an image sensor of a camera by inserting the additional optical element between the camera lens and the image sensor of the camera, wherein the center thickness of the additional optical element and the optical power of the additional optical element are matched to one another in such a way that, for a predetermined diaphragm setting of the camera lens, a flange focal distance defined by the camera lens remains substantially unchanged by the inserting of the additional optical element.
A lens system comprising a camera lens which can be selectively coupled to a camera and an additional optical element with a positive optical power which is insertable between the camera lens and an image sensor of the camera, wherein the center thickness of the additional optical element and the optical power of the additional optical element are matched to one another in such a way that, for a predetermined diaphragm setting of the camera lens, a flange focal distance defined by the camera lens remains substantially unchanged by the insertion of the additional optical element.
