These lenses are mentioned quite frequently on this and other boards. I own and love my 90mm WA Raptar, but different postings, on various boards give conflicting information. Some sources say the 90mm Raptars are of similar construction as the WF Ektars. A double gauss 4 element air spaced design. While others give construction similar to the 90mm Angulon, a six element two group dagor. Not that it makes much difference, it is just a couriosity, but if anyone knows, or if you can point me to a source of information.
Thanks in advance.
Jonathan

| Any Wollensak fans out there just dying to pull out an old catalog from their collection and let me know the construction of this lens? Or how about the 65mm f/6.8 Optar? There's got to be someone that knows. |

The Lens Collector's Vade Mecum says it is a four glass gauss type. Why don't you take yours apart and put yourself out of one misery and perhaps into another?
Cheers,
