This auction is for a VOIGTLANDER SEPTON 1:2/50mm VINTAGE CAMERA LENS FOR BESSAMATIC ULTRAMATIC
"The Septon is, according to common knowledge, a modified version of the Ultron lens previously made by Voigtlaender for their rangefinder system.
The need of adapting the lens to reflex distance, and surely also budget reason, called for a redesign of the lens, that moves from an Ultron design (double gauss) to a hybrid design, always of seven elements (hence the Septon name), that has parts of Ultron and, with the cemented double, some Sonnar echoes.
This makes of the Septon a unique lens in the 50mm panorama, well worth the attention of the old lenses fans...." MF lenses.
