Large Format 4 x 5 f 4.7 lens kit, 150mm 210mm 175mm with Copal No. 3 shutter

Description: I am not a dealer, I am a photographer selling my personal gear. This is a rare opportunity to own a matched set of large format lenses as well as a piece of photo history. This large format kit includes three lenses and a shutter, just the way I bought them, I did not put thiskit together. I had this Copal 3 shutter serviced at Grimes where they also updated the aperture scale ( blue tape ). According to history, in 1991 a Carl Zeiss factory was sold to Bernard Doctor who made Tessar formulated lenses under his company name, D. O. Industries ( Doctor Optic ). Glass is clean and clear, shutter fires at all speeds and has a flash synchPlease look at the pictures closely as they are part of the description.Graflex lens board included The complete history is below. After the German reunification in 1990 the East German Carl Zeiss Jena combine, which was quite big (70,000 employees), and made everything from binoculars to microelectronics in the GDR, was downsized and separated into different parts. Docter Optic was originally a small West-German company founded in 1985 by Bernhard Docter (hence the company name – no relation to academic titles). Note the spelling of the name: Docter, not Doktor, Doctor, or Doctar - the latter is one of their lens names; and Optic written with a “c”. They made OEM projection optics, lighting optics, car headlight optics, etc. Their specialty was a glass blank molding process for aspherical optical elements. They were located near Wetzlar. The company expanded, and in 1989 bought an Austrian subsidiary, which had originally been the optics department of Eumig, an Austrian manufacturer of home movie projectors. The Docter Optic group bought some of the plants of the former Carl Zeiss Jena combine in 1991. In August 1991, Docter acquired the plant in Saalfeld, Thuringia, which had made the Carl Zeiss Jena large format optics in the GDR, and was still producing them then. He also bought another former Zeiss plant making binoculars in nearby Eisfeld at the same time. From 1991 to 1995, Docter Optics continued the GDR Carl Zeiss Jena (CZJ) lines of large format optics (Tessar, Apo-Germinar) under the Docter name, and started bringing out new lenses (the 65mm Doctar WA wideangle lens) shortly before the bankruptcy. After the bankruptcy or at the latest after the sale to the Rodenstock/Bosch/Hella consortium they stopped producing LF lenses. In 1997 Docter offered their remaining inventory of large format lenses on their web site (removed in early 1998), mainly for wholesale. Badger Graphic had some of those lenses for a little while, but they are long gone. As of July 2002, Mr. Cad in Croydon, UK, still has a few new Docter lenses listed (check under “Doctar”). Docter offered all the lenses (except the 65mm) both in barrel mount and adapted to Copal shutters. For this reason, the long focal length have two different maximum apertures, depending on the mount. Note that sizes, weight, and filter threads are often different for barrel and Copal versions! Tessar/Doctar These are direct descendants of Paul Rudolphs Tessar from 1902, with 4 elements in 3 groups. Note that the first years after Docter Optic acquired the plant (1991), they were sold as Docter-Optic Tessar, later the name was (had to be?) changed to Doctar. They came in focal lengths from 50mm to 360mm, with a maximum opening of f/4.5, except for the 300mm and 360mm in Copal 3, which are limited to f/5.6 and f/6.8 by the shutter. All Docter LF lenses, except the 65mm Doctar WA, were originally designed by and for Carl Zeiss Jena, and older ones are marked that way.
