Front element loose in CV35/2.5

[finitud]

Hi All,

I have been happily shooting an M2 with a Cosina Voigtlander 35mm f/2.5 for a month or so now. These last few days I've noticed that the front element of the lens (where the aperture ring is located) is noticeably loose and wobbles a little. I'm a bit concerned that something's wrong or that it's going to drop out of the lens (doubt so, but... 😱)

Has anyone had a similar issue? Should I take it to a repair shop? Is there an easy way to fix it? I haven't found any screws on the lens!

Cheers!

There is a retaining ring in the back that you need to tighten.

mine has it to a little, never got me worried though.
But do you need to open up the back of the lens? Is it easy? Or when it is working just fine keep it like that because the opening of the lens might do more damage....?

I have only done this for the 35/2.5 PII. It's real easy, you can access the span ring in the back without lens disassembly. If that is the culprint.

Thanks! I will try tonight and post results.

It worked and was really easy to do! Thanks again for the tip.
