    Re: Converting a speed graphic into an SLR

    I think your biggest challenge is going to be working out how to detach and reattach the rear of the bellows when you convert from Press camera mode to SLR mode and back again. Everything else has...

    Re: Greetings from Melbourne (Australia)

    Hello! Probably more of us Melbourne LF people around than you would think.

  3. Re: Durst Componon and Componon. What is the difference?

    Kind of been here before, but that was not what Linhof did. There was no pool of lenses to pick from, Schneider manufactured to order and delivered a batch of lenses. As per Bob's explanation in a...
  4. Re: Durst Componon and Componon. What is the difference?

    There shouldn't be any noticeable difference, they are built to the same specifications.

    Re: 300mm Symmar-S transplant

    If your existing mount has the aperture scale marked on it all you need to do is measure the aperture diameter and transfer it to the new shutter. You don't need to derive the f/stop from first...

    You could buy them new in a Compur Electronic 3, but that didn't change the maximum aperture. f5.6 is the maximum aperture for that design regardless of how it is mounted and a number 1 shutter is...

    The Komura 33mm f4.5 fish-eye for 4x5 definitely exists in the catalog, maybe not in the outside world.

    To slightly rephrase what Mark has said about correction, the manufacturer could choose to correct for best results with the indvidual cells or best results with both cells together. As I understand...
  9. Re: Doubts about Schneider Tele-Xenar 360mm 5.5

    To confuse things slightly more; when the Compur 2 and Compound III, IV and V became unavailable Schneider responded by using the next shutter size up with adapter rings/bushes to make up the...

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

    At a guess, it means it was available in either a Compound III/7 or a Copal 3. See the one directly below it the lists a V/12 + 5FS, that would be a Compound V or a Compur-Electronic 5S.

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

    That era of Tele-Xenar would have been in a Compound III/7, which is the same as the 300/5.6 Symmar. Overall length is given as 110mm or 111mm in a few different brochures from the 50s and 60s. The...

    Re: Compur Electronic 3 repair

    There is a reprint of the repair manual for sale on eBay at the moment. I won't link to it, but a search on "Compur Electronic" should find it for you.
  14. Re: Large and rather interesting Schneider Optik lens in large shroud or barrel???

    It is a Vario-Claron (242-258mm), so some sort of industrial lens. A photocopier lens is a good guess.
  15. Re: Which would be easier to build - 8x10 SLR or TLR?

    The Gowland SLR is a much simpler beast than a Graflex and would be something that a reasonably skilled person could hope to replicate. The drawback is that has a single speed shutter, meant for use...

    Re: Komura/Komuranon 500mm f7

    I don't think they are convertible in the manner of an early Symmar where you remove one element, rather they have interchangeable elements like a Nikkor T 360/500/720
  24. Re: Angulon 18.5cm and 25cm combined lens in barrel

    I've got a catalog from 1931 which includes a table for converting Angulons. The 120mm Angulon has a 250mm front element and 185mm rear element so i guess that is your lens.

    Re: G Claron 355mm Shutter

  28. Re: When did Schneider stop producing Angulons?

    1969 appears to be the last year that all of the focal lengths were in production. There were four batches of the 65/6.8 in 1970 and a single batch of the 90/6.8. The last Angulon was a 65/6.8 ...

    Re: Strange COPAL 3

    It would certainly appear to be a Copal 3s which had a M56-0.75 internal thread (vs M58-0.75 for regular Copal 3). This is just fractionally larger than the Compound 3 (55.69 x 40 tpi) which would...

    No, the native shutter for the 360 Symmar is the Compound 4 which will give you f5.6. You don't gain any speed going to a number 5 shutter. There wasn't a smaller version of the Compur Electronic 5fs...
