  1. Re: CZJ Biotessar 165 2.8 image samples and shutter question

    I think Corran is talking about some of the prototypes which were certainly not shown in the past catalogues. To learn more about biotessars, check the links below. They are well explained.

  2. Re: CZJ Biotessar 165 2.8 image samples and shutter question

    More pics of the biotessar on the Sinar copal shutter.
    No physical vignettes. I think Sinar copal shutter solution is much cheaper than remounting the biotessar on the compound IV shutter.

  3. Re: CZJ Biotessar 165 2.8 image samples and shutter question

    From what I know, the biotessar was not made in shutter mounts.
    There are some compound IV mounted biotessars but these were retrofitted later after productions.

  6. Re: A custom made bag example for arca swiss 8x10

    I used to have a Sinar X and hauled around with it in the field.
    Soon I switched to an arca f-line classic 4x5.
    I think Sinars need the disassembly to make it compact upon carriage.
