Shutter size for Super-Angulon 90mm f8

[Luke Spadavecchia]

Hi Guys and Girls,

I recently purchased a very nice clean Super-Angulon 90mm (f8 version) mounted in a defunct Compur electronic #1 shutter. The shutter is not working properly, and does not fire at any speed other than its top speed, even when supplied with a clean 4.5v from a lab supply. This does not particularly bother me, as I use a Sinar automatic behind the lens shutter system (which I love) and want to mount the lens in a suitable DB board. I need to remount the lens because unfortunately I can't just set the compur shutters preview lever and use the behind the lens shutter instead because the rear element of the lens projects behind the shutter plane by a few mm.

So my question is, is the #1 compur electronic thread equivalent to the copal #1 thread? It appears that the front thread of the compur electronic 1 is M40-0.75 and the rear thread is M36-0.75.

I've been offered a couple of #0 and #1 DB boards for sale and wonder what the mounting/calibration issues might be. I would rather save ££ by mounting the thing myself, but could always get it done professionally at a push. Also has anyone else used a super-angulon in a DB mount? Does the extra distance the DB mount gives you between the rear element and the film plane allow you to use this setup like a 'handy' i.e. do away with bellows all together and focus on infinity using the separation generated by the DB mount, standard, auto shutter and film holder?

Sorry for the barrage of questions, I thank you in advance for your comments and advice: This forum is an amazing resource.

From the data I have you need a Copal or Compur 0 shutter for the f:8/90mm SA.
Mounting a lens that short on an inversed sunken lensboard will give you very little room between the standards, if any at all.
My real advice is to get a flat Sinar lens board with a Copal/Compur 0 shutter and use the 90mm without the behind the lens Sinar Shutter.
Mind you, mounting the 90mm into a new (used) shutter means that it should be shimmed aswell, so you get the maximum image quality from the 90mm.
Actualy a job for a trained technician.

I use a f:5.6/75 SA on a sunken Technika lens board and Technika adapter board on my P2 and it works well with a bag-bellows.

Go to the Sinar site and download the Sinar Code, it is an invaluable source of information about the Sinar system.

A 90mm f8 SA is most commonly in a Compur/Copal 0, even the 90mm f5.6 lens fit's in the same shutter, however some of the lenses originally fitted to Sinar DB mounts / shutters weren't standard so you need to double check. Schneider list the early coated (not MC) lenses as being 0+1 shutters.

Find someone locally who has a 0 and a 1 size shutter and see which it fits, if you don't mind a 40-50 minute drive I can help

The 90mm f:8 Super Angulon was sold in several different shutters, mine is in a Compur #00. Then later they switched to #0, and some were sold in #01. The #01 has the same threads as a #0; the #00 is smaller and the #1 larger.

Thanks guys for all the responses so far. Just to reiterate that mine is currently mounted in a compur electronic #1, which as far as I can tell from published data is the same size as a copal #1, so I'm really confused! From the serial number, the lens was produced between November 1968 and July 1970 and is not the multi-coated version (at least, it doesn't have MC printed on it).

Ian, your offer is very kind, and I may well take you up on this if you don't mind, although I will be away now until the 3rd of June.

Is it possible that someone had a conversion ring made up to mount the lens in the electronic shutter, which was probably pretty fancy stuff when new? I can't tell because I don't really know what the threads of the lens should look like! Anyway, thanks again. L

I'm off home to Turkey before that

There will be someone nearer anyway who can help.

Thank you so much Edwin, That is really kind. I have emailed you with my contact details. All the best, Luke.

OK, so my lens was a copal #1. Weird. Mounted it up in a DB board that I Frankensteined from a lovely new one and a golden oldie and all is great; thanks to Edwin for being a real champ on this! Thanks to everyone for contributing. L

I realize this is a pretty old post, but I recently acquired an older Linhof super Technika III( I feel like I probably paid too much, but that is a subject for a different thread). it did come with 4 lenses though, and original matched cams and focus rails. Anyway one lens is/was a super Angulon 90mm F8 My sample is shuttered in the "dreaded" 00 size.
Does the threading on the lens cells themselves vary, or is it the threading on the various sizes of shutter where the change occurs, or both? the lens cells themselves are very clean. I also own a modern Nikon Sw 90mm f8, so the Schneider will likely only get used for a couple of "real world" comparison shots. Should I sell it as-is, or get it re-shuttered?
any thoughts are appreciated.
Thanks.

#00, front and rear tubes threaded M22.5x0.5, tube length 16 mm.
#0, front and rear tubes threaded M29x0.5, tube length 20 mm.

If you want to use y'r 90/8 SA in #00, have the shutter overhauled. Reshuttering the cells in a #0 will cost more than the result will be worth in use, especially since you already have a 90/8 Nikkor.

Keep you're eye on Ebay, shutters do get listed I've found Prontor SVS #00 shutters quite cheap. I picked up a couple of "new" #00 Compur Rapid shutters, at a camera fair for £10 ($14) one won't latch both have plain (un-engraved) aperture scales. What you need to watch is not all Compur and Prontor shutters have a cable release.
