Theofanis Kavvadas Posted November 14, 2019 Share Posted November 14, 2019 Hi all, I just purchased a set of Oberkochen Opton S16 lenses, all T1.3. Body says: Made in West Germany. From the looks of them, it seems almost like they were never actually used. Now, I can't find any information about these lenses online or how they differ from their newer siblings - or are they even regarded as Zeiss? Furthermore, the set has 9,5mm, 12mm, 16mm and 25mm but is there also a wider than 9,5mm or longer, like a 50mm lens, to be found from that same generation? Thanks in advance, Theo Link to comment Share on other sites More sharing options...
Philip Reinhold Posted November 14, 2019 Share Posted November 14, 2019 I remember we had a rental in Berlin which owns Oberkochen S16 optics. I used them and mixed them a lot with Zeiss MK2/3 on student projects. I was told that there are Zeiss optics and only named Oberkochen for political reasons in the divided Germany in the early 80s.

Premium Member Dom Jaeger Posted November 14, 2019 Premium Member Share Posted November 14, 2019 I think the Oberkochen Opton name was used to brand West German Zeiss lenses when sold in the East Block, to avoid copyright disputes with the East German Zeiss Jena. So the lenses should be the same as normal Zeiss Super Speeds produced up until re-unification. Do yours have the triangular iris? If so there was a 50mm also made for S16, but no wider high speed focal length exists. Link to comment Share on other sites More sharing options...

Theofanis Kavvadas Posted November 14, 2019 Author Share Posted November 14, 2019 Thanks for quick responses! The lenses I bought have a regular iris. So which generation are they comparable with? Link to comment Share on other sites More sharing options...
Philip Reinhold Posted November 14, 2019 Share Posted November 14, 2019 Hmm the MK1 have 6 blade hexagon iris. Only meter or feet scale, different Front Diameters and arri-B mount (Possibly adapted to PL & upgraded with 0.8 Focus Gear) I own a set & love them. Mk 2-3 have Triangular Iris, 80mm Front Diameter. MK2 still got Arri B Mount and 0.8Focus Gear MK3 have PL Mount and 0.8 Gear on Focus & Iris. Link to comment Share on other sites More sharing options...
