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. This lens had an extra concave front element making it a 7 elements in 6 groups lens [1]
