I have one of these strange Xenar Type D lenses. It is a 165mm f/3.5 triplet with nice OOF rendering. I have found a few threads on this site and others relative to these lenses. Ole seems to have a 150mm and there is a 180mm for sale on Camera Eccentric. Are there other people actually using theses lenses? Apart from the two lines featured in the Vademecum, does anybody have more information about these rather unique Xenars?
