Unfortunately, something else is damaged with that lens, yet for display it’s nice enough. I have just finished work on a Wollensak Ciné Raptar 25 mm, f/1.5. Well done there’s no danger of graphite falling off onto the inner glass. After mounted back in place, usually the first step of assembly, closed iris gets wiped over with a soft little toothbrush on both sides. Then everything checked, adjusted, and dusted over with graphite in a plastic bag, excess graphite shaken and pounded off, carefully. For the interested, it takes a thorough cleaning, degreasing, and drying.

Rodenstock UV-Rodagon f5.6/60mm + 105mm + 150mm Pentax Ultra-Achromatic Takumar f5.6/300mm Pentax Ultra-Achromatic Takumar f4.5/85mm sold under their name with an additional designation were from Wollensak.ĭesignations were Eymax, Extol, Anate, Telate, Anpax, Acura.

All the taking lenses the Bell & Howell Co. An error of mine, it’s the third element that is unusually thick, not the fourth. on the barrel are nothing else than this Wollensak. The Eymax 6 inch f/4.5 telephoto lenses sold by the Bell & Howell Co., Chicago with Made in U.S.A. Life is too short to let us try every lens! The best lens is the one you have with you.

List of Rodenstock Interchangeable Lenses for 35mm cameras with Serial Numbers As far as I know, the Kodak 6 inch f/4.5 sharing more or less the same design.

Most of these lenses are simple telephoto which is similar to Bis-Telar.

Please feel everybody free to ask questions, I shall answer them as good as I can. They’re really on the short side of things. The pivots consist simply of the stamped-out material, how bold is that! Believe it or not, the little crowns make a rather snug fit with the driving cage but at the price of some uncertainty. Took the chance to repair it and found this special make. It was in disorder, wouldn’t work at all. More parts, seen from the opposite direction.Īnd now let’s have a look at the diaphragm. The shiny tube on the left is made from brass and chromium plated. So I leave both assemblies, have them cleaned, and can lubricate the moving parts lightly. I should have to bend it back inwards which I dislike. The two groups on the right I am not able to disassemble, the left one is heavily lacquered and the right one has an inner tube crimp-locked.

Said to myself I will toss the thing in a bin if the glass has suffered. Have just disassembled one such lens that showed ugly stains on the back of the front lens or group, something you can’t tell from trying to peep inside. In other words, a cemented doublet or achromat in front and another cemented rear doublet. I only want to share the fact that these are a four-elements design, basically an asymmetric Aplanat like the Busch Bis-Telar of 1905.
