    Re: Collodion websites closed

    I am still mourning the loss of Szabo's site. I wasn't much interested in their version of authenticity, but the knowledge there was amazing.

    Re: 30cm Heliar on 4x5

    I have a standoff board that allows a 30cm Heliar in shutter to be used with a 5x7 Canham, but its weight overwhelms the camera. It works great on an 8x10 Deardorff with a 5x7 reducing back.
  3. 75 Zeiss Biogon mil. surplus barrel lens - sketch for mounting into Copal 1 shutter

    Ive been trying something similar, albeit in plastic: 3-D printing an adapter for 3 Goerz Hycon cells, which I picked up unused 15 years ago. This is my first version for a #3 shutter. Id rather...

    I have done pretty well with 1" openings. Any larger and you spend too much money on silver nitrate, and smaller may cause scrapes on the top of the plate as you move it in and out. You also need to...

    Re: Elwood enlarger

    Yes, I had a 5x7 Elwood that had a piece of round glass ground in the middle to serve as a center filter. As I recall it fit into the dome, above the negative holder.
  6. Re: Durst Nega 138 alternatives?

    The Nega138 carriers are not that rare, keep at it and you will find one. There were also aftermarket carriers which were made for them. I use a Carlwen for 120 and 35mm roll film which I like. They...

  8. Re: any sources for custom size lens caps?

    I make my own leather lens caps. They are easy to make and look great. I found instructions to do them in Tomosy's Restoring Classic & Collectible Cameras. (Hint: Amazon's preview shows pages 10 and...
  9. Re: How to remove heavy casing from 24" Aero Tessar

    I have one, and Dan is correct, the cells just unscrew from the barrel. For what it is worth, the barrel for this lens and the Kodak 12" f2.5 and the Eastman 13.5" f3.5 aerial lenses are the same.
  10. Re: Rebuilding a Deardorff 11x14 Studio Stand

    I am also going to order (three) bellows from them... Perhaps they will give us a break on multiple orders? If anyone is interested let me know and I can reach out to them.
  11. Rebuilding a Deardorff 11x14 Studio Stand

    Having a bit of time on my hands, I replaced the felt on the stand. "Craft" felt, which is a synthetic and wool blend, seemed too thin and loose for this so I found high-quality 100% wool felt...

    508mm f/7 ILEX lenses

    Based on the conversation here I picked up one of the 20” f7 Ilex lenses. I can now verify that it is indeed a Tessar, not a triplet, as witnessed by the doublet rear element. This also verifies...

  17. Re: Rebuilding a Deardorff 11x14 Studio Stand

    I can't imagine that they went out of factory with two different brakes on it, so someone must have swapped the parts at some point. Regardless, my experience with the stands is that they are very...

    Re: Goerz Dagor SV?

    Years ago Geoff at Lens & Repro showed me two Goerz lenses with the name "Dagor" on them that were not dagor designed lenses. He said that one was a plasmat and the other was a dialyte.

  25. Re: 152mm f/3.5 & 2.8 KOMURA experiences wanted

    These lenses are very similar to the 150/2.8 and 135/3.5 Xenotar lenses, and 135/3.5 Planar. Both Komura lenses fully cover 4x5 without much movement. They do not increase image circle as you stop...

  27. Re: 8" Dallmeyer Pentac f/2.9 - Any Users?

    Randy, these are pretty soft (flare actually) open wide, so try yours before trying to dial in any additional softness. Its a nice look, I think. As mentioned above, these never had radioactive...

    Yes, the platform is working well now, thank you. The posts were not the problem, the chains were too loose.

  33. Re: Rebuilding a Deardorff 11x14 Studio Stand

    I would certainly try using the piece you already have first. If it fits around the posts I would think it should work well enough with some felt glued to it.
  34. Re: Alternative to the Schneider Xenotar 150mm F2.8 for 4x5?

    I have used a 152/2.8 Komura. It was a fine lens, very similar to the Xenotar, but harder to find. I was less pleased with the 135/3.5 Komura I owned, and found it more prone to flare than my 135/3.5...
  35. Re: Alternative to the Schneider Xenotar 150mm F2.8 for 4x5?

    ... and don't forget about f3.5 Xenar and Tessar lenses. For 4x5 you need at least a 180mm, if not a 210mmm. A faster 16.5cm f2.7 Tessar is also out there, but hard to find and designed for 3x4, not...
