Studio Television Lens 30x Variogon 2.1/16–480 mm, 1970 onwards

Schneider, Kreuznach, Germany. No. 12813274, dimensions: 41 x 17 cm, groundbreaking worldwide with the implementation of the 30x zoom in two variators for all television cameras. For 1 ? inch format, front lens clean, internally still in good condition, all mechanical elements movable, iris diaphragm opens only partially. – Note: The image circle is normally approx. 19 mm in diameter at a distance of approx. 68 mm (place for the prism) from the rear lens; with the variator set to 30, the image circle diameter expands to 35 mm. When you remove the covering, you can see the effort that went into maintaining the limits of precision engineering while maintaining incredibly smooth operation under all temperatures. Admirable, top-notch technology! An important exhibit, both for lens and camera technology, as well as for the history of media. First time at our auction!
