My Alpa archive has a list of all oude delft lenses available. I also have a spectros , Swiss lens inscribed "system old delft". probably some business alliance. The company seems to have gone into x ray imagining optics. wpoould be interesting if anyone here can supplement. |

Is this Alpa archive online? If so, please link to it. De Oude Delft aka Old Delft did make some lenses for the Alpa SLR system, I know of Alfinon, Alefar and Algular lenses. They also made lenses for aerial photography, named Deltamar f.i., night vision optics and lenses for optical systems for X ray machines, called RayXar. I once came across a 105mm f/0.75 Rayxar on a camera fair - a massive piece of glass, way too heavy for my kind of photography. |

Spoken Swedish is close to unintelligible to me, but written Swedish makes a reasonable amount of sense to my dutch eyes, so I would appreciate those Old Delft Alpa brochures. When you were suggesting that someone could supplement to your archive I assumed incorrectly that it already was in digital form.. |
