m-componon f4/80mm in barrel - can I attach the barrel into a shutter?

[Peter K]

Patrick, as one can see on the first page http://www.schneideroptics.de/archiv/pdf/m_componon.pdf
the M-Componon in the background is mounted in a shutter size #0. So the shutter is used as a back-shutter. To use the same shutter with another M-Componon, only unscrew the whole lens and screw the other lens in. It's the same as with switching between different enlarging lenses.

With the three small screws loosened, not removed, you can turn the lens in the mounting ring to avoid the f-scale is at the wrong side so you can read the f-scale
effortless. If the whole lens is turned in such a position, fix the screws.

Peter, thanks for trying to help me.

I have understood that the shutter should go behind the lens and that it should be a copal-0. But,the problem is that I am missing a piece (the tube) that will add some distance between the barrel and the shutter so that the rear lens element will not hit the shutter blades. The barrel with lens is shown if you follow the link in a previous post.

Did I overlook something?

Patrik you are right, you are missing this special tube. So ask the previous owner, possible he has used the lens with a different mounting and he don't remember this strange piece of metal in his drawer. Or ask at Schneider.

Good luck

Thank you archivue, I will investigate if this is what I need...I need to measure the threads on the back of the barrel a bit more precise to be certain.
