  2. Re: Doubts about Schneider Tele-Xenar 360mm 5.5

    I've received the ring from Rafcamera, put it on the rear cell and adjust to 110mm overall length.
    Now the image on the GG is sharp (it was very soft before and overall length was 102,5mm)....

    Re: 2 sheets of film in the same holder?

    You can eliminate back side emulsion
    Less density (more exposure needed) but more sharpness.

    Hello.
    I have a Meopta Magnola (13x18 field camera) but I don't have film holders to use in it.

    Does anyone know if they can be found, built at home or change the camera back to accept standard...

    Re: Lens board adapters thread

    Mine is Micro Technical Mark VIII.
    I have 3 original boards but the most lenses are mounted in homemade boards. I make them from dm with glued natural calibrated cork rails.

  11. Re: Doubts about Schneider Tele-Xenar 360mm 5.5

    Very interesting.
    Your shutter is some kind of hybrid. Mine is labeled as Copal 3 but threads are 56x0.75 (3s).

    Edit.
    Can you help me measuring f-stop numbers in this copal 3. I would need...

  14. Re: Doubts about Schneider Tele-Xenar 360mm 5.5

    You're right. I found in this book that "3" is the name that Mr. W. Voigt give to Compur Electronic 3. So it refers to the availability of the lens in both compound iii and compur electronic 3.

    I have found a table that says Compound III / 7 + 3.

    What does that "+ 3" mean?

    Re: Reversal vs negative

    I rarely use color negative but lots of chromes. Neither on 4x5. I use Fuji and kodak chromes on 35mm, 645, 66 and 67. I love them

    Price is my principal "con".

    Thanks for you reply.

    So your h1 (overall length) is 108 (aprox). Mine is 102.5mm and a friend's copy is 109.6mm.

    How about h2 (shitter seat to lens rear). Mine is 22.3mm. My friend has...

    Hello

    I've just bought one of these lenses. Serial number tell it is from 1954.

    Shutter is copal 3 but it isn't its original shutter (max aperture is 4.5 instead of 5.5. See pic #1. I guess...

    Thank you both for your replies.

    I forgot to mention that I'm going to use the lens on 4X5. That means I'll only use the central part of the coverage. Considering that RR are used as normal lenses...

    Hello.

    How would a Rapid Rectilinear design compare to this Cooke Triplet?
    I'm planning to build a very simple compact long focus RR. I don't have lenses longer than 300mm. I'm wondering how...
  25. Re: Does changing aperture move the focus point

    Another point: focus shift while stop down happens with convertible lenses when using converted. So seems to be related with alterations in the iris position or configuration. This barely occur with...

    Re: Too good to be true?

    You can use filters below the lens. I don't see benefit at all.
  30. Re: Is it possible to pre wash photo paper?

    Good point. A carefully located thin layer of transparent kitchen film could work.

  32. Re: Use of X-ray film: technical discussion with example images

    I was thinking in coating after processing, not before. So would be necessary to develop the film with extreme care. When dry I would spray one or both layers. This could help to handle the negatives...
