The original "Ultron" was a 50mm f/2.0 lens with 6 elements in 5 groups designed for the Voigtlander Prominent camera and introduced ca 1950. It was designed by A.W. Tronnier [1] as an improvement on his own Schneider-Kreuznach Xenon (c.a. 1937) design. Ultron lenses were also used in the Vitessa cameras, Vito III, Vitomatic and others as a high end option over the Skopar.
When Zeiss took over Voigtlander a further design improvement by Tronnier resulted in the Ultron 50mm f/1.8 used in the Icarex camera and also available in M42 mount (as Color-Ultron). This lens had an extra concave front element making it a 7 elements in 6 groups lens [2]
