Abstract: What is described here is an optical auxiliary system for a camera, which is arranged between a recording lens and a camera body and which comprises a relay system for projecting the image of the recording lens onto the film or the video pick-up.

Abstract: A supplementary optical system for a camera which is inserted between a photographic lens and a camera housing and which comprises a relay system for projecting an image of the photographic lens onto a film or a video recording material, wherein the relay system produces more than one image and a zoom lens is disposed on the camera body. The supplementary optical system permits focusing and other camera controls to be operated near the camera housing. Additionally, this invention can be converted for performing different tasks in a simple manner due to the employment of path bending units.

Abstract: A snorkel lens system having a first tubular member and a second tubular member or vertical relay tube, disposed perpendicular with respect to the first tubular member. A first axis of rotation is centrally disposed through the first tubular member and a second axis of rotation is centrally disposed through the second tubular member. The first axis of rotation is perpendicular to the second axis of rotation. The second tubular member or vertical relay tube can be rotated about both of the two perpendicular axes in two perpendicular planes to provide a three dimensional filming special effect.
