6 3/8" Focus Wollensak F4.5 Enlarging Velostigmat

[Nesster]

I lashed this old lens to a 135mm M42 lens barrel using gaffing tape. The barrel mounts on a Pentax Bellows II, which in turn goes via a M42/EOS adapter to a tilt EOS/Nex adapter, and finally to a NEX C3. Alternately I can go directly from bellows via the appropriate adapter to a NEX or Pentax camera.

A self portrait of the lens. I didn't use a tripod though I should have, but pig headed that I am I was determined to do this hand held
It is a 4 element Tessar type lens.

An advantage of this set up is that I can swap lenses simply by taping a different one at the far end... for smaller ones I use a bit of window insulating tape to press fit the lens inside the tube; this 6 3/8" is about the biggest one I can mount like this. I have some plastic pumbing that should be able to accommodate an even larger lens.

I also had a Kodak Anastigmat 6 3/8" f/4.5 4x5 mounted the same way; though inadvertently I taped over the aperture movement, so it was fixed at a bit smaller than f/5.6

I have several versions of this, some in barrel and a couple in shutter (Betax and Synchromatic).
Its a nice Tessar like most of the Wollensaks.
I think at the time there was no great difference between taking lenses and enlarging lenses.

My solution for mounting these is an M42 (or whatever your bellows is) T-mount with the inner ring removed, and longer set-screws screws fitted. If you have a jam nut/mounting ring for it, screw it in part way to give the T-mount screws something to bear on.
Stick the back in the T-mount and tighten the three screws, and there you have a rather firm mount.

Thanks, I think I'll try that!
