Lens cells for a Compur 2 shutter

[coisasdavida]

Hello all,

I have here a 240mm/5.5 TeleArton that came in a very nice #2 shutter.
The lens cells very damaged (scratches) and I don't appreciate tele lenses.
So I was starting to think I could maybe look for cells that would fit this nice shutter.

So far, my Google searches have taken me to a few post here and at Apug and I found that these would fit: a 165mm/6.8 Angulon, a 240mm/5.6 Symmar convertible, and a 180/4.5 Xenar.

I already a 165mm Angulon and a 180mm Tessar from Jena that should very similar to this Xenar.

Does anyone knows something interesting that is not a tele lens that would fit this shutter besides a 240mm convertible Symmar?

Are you sure you don't want a 240/420? I happen to have cells minus the shutter.

Ok, we can talk about it, but I still would like to know other possibilities! Thanks!

As far as lenses simply screwing into the shutter, there are two critical dimensions - threads and spacing. Both of these must match the shutter the lens cells were originally mounted in, this holds for all lenses and shutters. The Compur 2 was discontinued some 40 - 50 years ago, and I'm not certain it was standardised as were the other sizes, i.e. Compur/Copal 0, 1, and 3. The Compur 2 has somewhat of a bad reputation, somewhat undeserved, because it's as good functionally as any other Compur - which is to say very, very, good.

Yes, spacing seems like a big problem.
On SKGrimes website they describe one Compur #2 as having 26.5mm length (cell spacing).
On Ole's post here on LFPF he gives a 25mm length.
My shutter is at 25.5mm.

Most -- but not all -- Repro Claron 305's fit very nicely. Terrific lens if you shoot 4X5 or 5X7.

I have two lenses in two different Compur #2 shutters: an 18cm f/4.5 Xenar and a 210mm f/5.5 Hugo Meyer Doppel-Anastigmat, and they are nowhere near interchangeable. The Xenar cells are much larger in diameter than the Meyer cells. The mounting flange thread diameters are different as well. So I suppose it depends on which Compur #2 configuration you have when it comes to which cells will fit.

My 355mm f9 Repro-Claron is mounted in Compur 2, and I do have a spare shutter for it as well.

I have used it on 8x10.

The Compur 2 came in multiple thread and tube sizes although yours, the Compur 2-5/II (aka Compur II 5/2), is the commonest one that Schneider used. The post war 165 Angulon, 240/420 Symmar, 135/3.5 Xenar and 150/2.8 Xenotar all use that shutter. The 180/4.5 Xenar used the larger Compur 2-6/II. I have a 1935 Schneider catalog that lists a Compur II, Compur IIS, Compur II 4/2, Compur II 5, Compur II 5/2, Compur II 6/1 and Compur II 6/2 so it is a bit of a minefield.

Don't know about that particular version of the Compur #2, but I have a 14" R.D. Artar in a Compur #2 (not sure which model Compur #2 though). Makes for an extraordinarily light weight lens ideal for backpacking.
