Thank you UncleVanya, I notice that I need to be a member for at least 3 days and have posted at least 2 forums posts. So I will edit this post when I eventually see the 'Edit message' button.

Thank you very much for the explanation, interesting and this would explain why its only my two DDR lenses with the problem of wobbling :) As for lubrication, I was referring to the focus ring on the Zeiss that is a little more stiff than my Takumars hence why I noticed the wobble. I read this is common in lenses of that era from the DDR and russia.

I would happily update the title of this topic to be more accurate and or delete this thread if this is deemed an unnecessary or too dangerous a fix, but I cannot see a way to edit or delete the thread / post

Thanks for the replies and thank you for the welcome. I admit this is a gutsy first post and this should be done with caution as I appreciate the possible negative side effects of using anything sticky.
Sorry Stevebrot I am not completely sure what you mean by the 'snug up to the register" feature.
I guess I was not happy that once the adapter clips in, there is still a very small amount of movement in it. Not a problem on well lubricated focus rings, but on my Zeiss it was becoming a problem. This solution still allows the adapter to clip in and behave as usual, just a little tighter than without the little tape strips.
I agree it's not without its dangers and is not for everyone :) Maybe a redundant post, but I couldn't find a solution that addresses the problem in this way without introducing additional bits to the lenses and therefore things to loose.
But I appreciate you both taking a look and the feedback :)

Hello all,
Here's my first post, but I wanted to show my findings for anyone who has experienced the same problem.
So I'm primarily a M42 mount lense shooter. I rarely use anything other than Old screw mount lenses. This is great but it poses a few problems when it comes to adapters.
I have gone through a aftermarket adapters which either fitted snuggly, but had loose threads or had tight threads but didn't fit snuggly at all, so I resorted to buying the Official M42 adapter ring from Amazon to see if it helped.
It worked great on my Takumars which sit snuggly against the body, but it was a problem for my Zeiss lenses which although screwing all the way in, showed a little movement that is in the design of the adapter.
So, rather than modifying the lense, I looked at ways of modifying the adapter to ensure a snug fit into the body and prevent any movement of the lense.
Below are instructions on how I fixed this. Note: I accept no responsibility for any damage to your equipment as a result of performing or using this fix.
This fix will use tiny strips of tape to increase the amount of friction between the body and the adapter.
Firstly, you will need:
- Duct tape
- Official pentax M42 adapter (not shown here)
- Small, sharp scissors.
- Small flat head screwdriver

We will be sticking the tape on the outside of the adapter ring behind the little 'runners' shown below

So, firstly, we want to cut a piece of duct tape off and then, cut it down so it it approximately small enough to fit on the outer edge of the adapter ring.

Then stick this down on the outside of the ring as shown below, using the flathead screwdriver to ensure the tape is fully stuck down.

Do the above steps for all three of the runners found on the adapter, then, all you have to do is fir the adapter as normal, this will likely be a bit more snug than usual, but persevere and the adapter will clip in as normal. To take out the adapter, I recommend the removal tool supplied by many aftermarket adapters, or the usual pen method recommended by Pentax with a little extra umph.
And that's it, my Zeiss lense now has no movement whatsoever and so isn't a distraction when shooting.
I hope this helps. Any questions, do just ask and I will try my best to answer them.
