History
A. Schacht of Ulm, a maker of lenses for Exakta and Edixa, supplied Pignons with two: the Alpagon 35mm f/3.5 of 1958 and the Altelar 90mm f/2.8 of 1957. The Alpagon is a six-element retrofocus wide-angle in three groups with an automatic diaphragm worked through the Alpa coupling arm, stopping to f/22 and focusing to 70 centimetres — the Alnea catalogue’s wide-angle before Schneider’s Curtagon took the place around 1960. Production is unpublished; the lens is scarce enough that no review of it has been found.
This history is AI-written, from the sources listed at the foot of the page. Where the record is silent it says so rather than filling the gap — but no human wrote these sentences.
