    Re: 14x17 Tessar Series IIb worth fixing?

    Years ago Bert Saunders sent me instructions for cleaning B&L Tessars' in barrel diaphragm mechanisms. Here's a link to it: https://1drv.ms/u/s!AggQfcczvHGNgkP30QQrY1NPA1aA?e=yUaHiY

  8. Re: Cambo sc and Schneider 90mm f/8 Super Angulon Multicoated focus problems

    Agree pretty much. After the OP sets the camera up properly and finds that the bellows contrains movements intolerably, then it will be time to shop for a bag bellows. But first things first, and...
  9. Re: Cambo sc and Schneider 90mm f/8 Super Angulon Multicoated focus problems

    Yes, but they come closer than needed when set up normally with the tripod mounting block positioned in front of the front standard or behind the rear standard.

    The OP should set the camera up properly before shelling out for a board that's not needed.

    No, cells that fit an EKCo Ilex won't fit one supplied to other Ilex customers, and vice versa.

    Um, Robbie, I b'lieve that the EKCo Ilexes have different internal, not external threading. Could be mistaken.

    As I suggested, older lens in newer barrel.
  22. Re: G-Claron 150mm f/11 - Any info appreciated

    lasse, measure the diameter of the entrance pupil with the aperture indicator at 9 and at 11. Divide the measured diameters into 150 and tell us what you got.
  23. Re: G-Claron 150mm f/11 - Any info appreciated

    There are two versions of G-Clarons, the earlier dagor types and the later plasmat types.

    I have a dagor type 150/9 G-Claron with a higher serial number than yours so yours should be a dagor type....

    Re: how to work out shims

    If it came with the lens it is what's needed. The only thing you have to do is not lose it if you move the lens to another shutter.

    OP, where is this shim you mention? If it is between a cell and the shutter, it is there to compensate for a slightly off-specification cell. If it is between the back of the shutter and the lens...

  31. Re: How to Calculate Bellows Extension correction for a true Telephoto lens?

    Iga, a lens' focal length is the distance from the lens' rear node to the film plane when the lens is focused at infinity. Telephoto lenses' rear nodes are in front of the diaphragm, not behind it,...

    Interesting if true. Unfortunately not true.

    I just looked at a couple of H'blad data sheets for early and late 38/4.5 Biogons. Both show the same focal length, 38.6 mm.

    Probably not.

    Flange-to-film distance given focal length depends on the lens design. For example, my 101/4.5 Ektar, a tessar type, has a larger f-to-f than my 105/3.7 Ektar, a Heliar type. To...
