Help on Summicron DR please.

[Fabian]

Hello


The front element, the part with all the glass in it moves a little bit if I touch it.
I don't know what to do, because the whole thing is screwed into the back part of the lens.
Does anybody know how to tighten that.

I appreciate all input.

If it's built like my 60s rigid Summicron:

- if only the front element (the first glass element) moves, tighten the front ring (the one with Summicron written on it).
- if the entire front barrel moves, you can tighten it from the back.

You need a lens spanner for both.

Maybe it's time for a CLA by DAG or Sherry. Not to expensive when you consider the value if this lens.

I would not screw around with it (pun intended). If it's in that condition it's likely time for a CLA and "check-up" anyway. Send it to her, she'll likely charge about $65-95 USD and the lens will come back working like new and not need another CLA for 5-10 years.

Oh, and great lens BTW, perhaps my favorite in Leica-mount.

From your description, I have a hard time telling if you mean just the very front element is loose, or the enbtire module. Roland's advice is good for either case.

The DR Summicron has an optics module that screws into the focus mount. On my Type I Rigid Summicron, The whole thing just screws into place by hand. The DR and Type I summicrons have identical lens modules.

Thanks for all your quick help.
It is actually the whole front module. I will give it to a guy in my town, it looks like an easy job.

Thank you

But it's supposed to unscrew, to go on the Visoflex. I unscrew mine all the time. :)

Last time I gave my Rolleiflexes to a "guy in my town" I sincerely regretted it. Later everything ended up going to one of the renowned and trusted experts and I paid all over again to have it done right.

Be sure he REALLY knows what he's doing.

If it is the whole optics module, try screwing it back into place. As stated, This is a normal function of the DR summicron.
