The new Biotar 75mm f/1.5 lens will be available for Leica M mount (with rangefinder coupling)





A few days ago I reported rumors about a new Biotar 75mm f/1.5 lens - I can now confirm that this lens will be released soon. The new lens will be available in Leica M mount and will have with rangefinder coupling. I will have more details next week, so stay tuned. Here is some additional information:

  • The Biotar name is registered by Globell - a subsidiary of net SE group, who is the company behind the Meyer-Optik Görlitz brand.
  • The new Biotar 75mm f/1.5 lens is created in collaboration between Meyer-Optik Görlitz and some other well-known names in the industry.
  • Production of the lens is not going to be done by Meyer-Optik Görlitz.
  • I was also told that an award-winning designer who used to work for Leica is on the Biotar team.

Here are a few pictures from old Biotar 75mm f/1.5 lenses:

    I’m not so sure Meyer-Optik Görlitz are manufacturing or even final assembling any lens. They belong to a software- and trade-oriented group with a heavy focus on sourcing, marketing and distribution.

    The Biotar’s first cousin, the Emil Busch Glaukar 97mm f/3.1, is manufactured by Uwe Weller Feinwerktechnik GmbH.

    • This is probably the company that will make the new Biotar as well.

        And Uwe Weller Feinwerktechnik (which has had long ties with Leica) has recently relocated at the new Leitz Park.

        An ancient Zeiss lens which might be made at a brand new Leica plant. Talk about irony …

        • Yes, I think they also make the Leica cinema lenses.

          • John-F

            I think you are right. Have a look at their product page (German):
            http://www.weller-feinwerktechnik.de/de/inhalt/produkte.html

            We can clearly see the side view of a Summilux-C cine lens – but even more incredible, we can see the cross section of a Leica Summilux-C lens!!

            No one in the cinema lens industry has ever published any detailed info (design wise) about their lenses! 14 elements in 10 groups if I am counting right … This is quite a scoop!

          • John-F

            Oups sorry… make that 15 elements in 12 groups! Not to mention the many aspherical surfaces.

            This lens is far more complex than either the Zeiss Otus 55mm or the Summilux-TL 50mm Asph.

          • thanks, I will share this picture on social media

            ‟I was also told that an award-winning designer who used to work for Leica is on the Biotar team‟

            Could this person be Lothar Kölsch, who left Leica Camera several years ago?

          • I guess we will find out next week.

    By the way, the optical drawing in your post is that of the Гелиос-40 (Helios-40) 85mm f/1.5 calculated in 1950 by Д. С. Волосов (D. S. Volosov) on the basis of the Carl Zeiss Biotar 75mm f/1.5, not that of the Biotar itself 🙂

    • close enough 🙂

  • abortabort

    The other remake lenses have been of zero interest due to the lack of RF coupling. So this is a nice change.

    • Yes, this is a good move.

  • Helios

    Cool lens. Can’t wait.

    “award-winning”…
