I have just purchased what appears to be a Rodenstock Clarovid at a flea market in Ottawa. It has a coupled rangefinder with separate sighting window from the rangefinding sight, which makes it a Clarovid I. From what I gleaned from the web, the camera body is identical to the Welta Solida. The leatherette does not have "Rodenstock" embossed on it, but perhaps it was replaced at some point. It is in very good condition for such an old camera, and some scratches on the retaining ring around the rear lens element suggest it was serviced. Everything works, even the self timer and the slow shutter speeds, however the entire Compur shutter and lens assembly can rotate freely with respect to the bellows and front standard, which makes it difficult to set shutter speed and cock the shutter without using another hand to hold the assembly still. Amazingly it is still light tight even with this problem. I cant see any screws or other means to secure the shutter to the standard. The rear assembly appears to be screwed solidly into the front, but I still see about 1 or 2 threads exposed between the front standard and the shutter assembly. Does anyone know if there is supposed to be a means of securing the shutter/lens solidly to the front standard, or perhaps it is just screwed tight and mine has stiff threads and is actually not tightened up. I have put a film through the camera yesterday; it's light tight, but I have not scanned it yet to see if the lens is actually sharp. (The lens is marked Rodenstock Ysar f3.9 10.5cm. Appears uncoated. From the serial number, I date the camera and lens to 1933.

hi hsandler:

sounds like a nice camera !

with the camera back open look towards the lens... is the a retaining ring loose?
sometimes they loosen up and the lens moves freely as you describe. if THIS is the problem
it is an easy fix ... with the camera lens in position the way you want it to be ..
open the back and turn the retaining ring to tighten the lens onto the front of the camera ...
you might have to fold the camera up to get better access to the ring withthe bellows compressed and back open
you should be able to tighten it without a problem.

have fun!

I have no familiarity with this camera, but some shutter bodies have a pin or screwhead in the rear mounting surface to key into a recess in the lens board to prevent rotation. You mention some screw thread showing and some indications the retainer ring had been removed. It occurs to me if someone replaced the assembly and didn't seat the "key" in the recess, the shutter would be spaced out and could could rotate and loosen. Just a thought -- if it applies in this case, the fix might be trivial!

Good luck with it, sounds like a nice find.

You mention scratches on the retining ring for the rear element of the lens. This is bad news - it means an amateur has taken it apart. A professional would not scratch the paint.

There are usually two rings here - the outer one holds the shutter housing to the camera and the inner one keeps the glass in place. Both need to be tight.

One of my folders does that at times, and I don't seem to recall it being a problem in the results. That said, you can look up threads on "spanner wrench" to see what you can find to tighten it if you like.

I have a 645 unmarked Rodenstock that I got on here that is also similar to the build of similar Weltas of the era, and it has given me some good images. Getting back the first roll on these old gems is so often a mix of hopeful wonder and feared dread, but in most cases, you'll find a great niche for the camera! Enjoy!

Thank you everyone. It was indeed the retaining ring inside the camera being loose, although it seemed tight at first because of all the old gunk on the threads. I tightened it as much as I dared using two jeweller's screwdrivers, since I don't have a spanner and that helped a lot, although there is about 10 degrees of residual rotational play. It's much more useable now. Scanned the first roll. Stopped down to f11 it's not bad; opened up, poor contrast. There may be a faint overall light leak. It seems like the negatives from the frames that sat in the film gate longer between shots are foggy overall. Time for some more electrical tape work around the bellow-lens junction I think. I'd post a photo, but I believe scans are not allowed here unless they are of prints.

You can post digital shots of setups, darkrooms, anything that's informative or illustrates your post, far as I know.

Also, the $14-ish spanners on Amazon and eBay get some dissing around here, but mine has been just fine (I don't fix cameras all day, handy when I need one).

I once made one with 2 screwdrivers, a couple grip heads and a piece of 5/8 boom stock, to get inside a mamiya RB lens… that was, umm, interesting...
