drk_1981 Posted August 25, 2014 Share #1 Posted August 25, 2014 Advertisement (gone after registration) Hi Guys, First, I know its not a Leica lens (neither has it Leica's build quality) but does someone out there have also a wobbling lens (my case: Voigtlander Nokton 1.4 35mm). If yes, what did you do to stop wobble it? It basically started wobbling from one day to the other. Overall I like the performance of it, therefore I do not necessarily want to replace it immediately with a 35mm cron (as that was planned for another 1-2 years and therefore not yet budgeted). If it has been send to CLA, how much did it cost? I'd be especially interested in this input from fellow continental european users. thanks for your feedbacks.

250swb Posted August 25, 2014 Share #3 Posted August 25, 2014 I have no idea what 'wobble' means, so can't say what the answer should be. Is the lens notchy and doesn't focus smoothly, or does the front element move around, or what? Steve Quote Link to post Share on other sites More sharing options...

Steve Hi Steve, yeah the whole front element is kind of loose by means that you can move the front like one / two millimeters to the left or to the right, therefore "wobble".

joeswe Posted August 26, 2014 Share #7 Posted August 26, 2014 Advertisement (gone after registration) Nothing wrong with Will van Manen, but you will end up paying around 30 EUR or more alone for postage to NL and back, for something which might be a very simple fix for any local camera repair guy or even for yourself. For example, it could be just one of the retaining rings in the back of the lens being loose, relatively easy to check and correct (don't ask how I know). Also, there are some internal screws in some of the Voigtländer lenses that hold together the optical assembly and parts of the focusing mount and can become loose (err, don't ask how I know ...). My advise would be to let your trusted local camera repair guy have a look at it. In case it turns out to be a more complex repair that necessitates spare parts etc., my guess is that neither he nor Will van Manen will be able to fix it. Then your only choice will be Voigtländer Germany (Ringfoto), who will send the lens to Japan. As the model is of current production, repair shouldn't be an issue (I understand, there have been problems with the repair of some discontinued CV lenses due to lack of parts). Unfortunately this is one of the not so ideal aspects of owning CV lenses and cameras: Having them repaired, at least in Germany. But don't worry yet, your chances are good that it is a relatively simple fix. Quote Link to post Share on other sites More sharing options...
250swb Posted August 27, 2014 Share #8 Posted August 27, 2014 Are there any tiny screws around the barrel that need tightening up? That's what you do with a 28mm Summicron after all. If you can remember how you were using it just before it started to wobble it may help, putting filters off and on, lots of lens changes, etc. to see if whichever bit you were grabbing may have loosened. You should also check the screws on the mounting flange and see if they are still tight, as I recall when re-centreing a flange on a 40mm Nokton when the screws are loose the other components of the lens also slacken off and that could be the 'wobble'.

drk_1981 Posted September 2, 2014 Author Share #9 Posted September 2, 2014 well, last night I decided to take apart the shell of the lens. For which I had to just unscrew 4 tiny screws. I did not know what to expect so i progressed with extra care that i do not destroy or scratch any glass elements. The whole thing is super easy to disassemble. 4 screws then the M-mount is lose and you twist it out of the socket as the whole lens body is like a big screw. second step was to tighten the M-mount and finally screw back those four tiny screws. HOWEVER, there is no marking how to put everything back in. therefore if you do not pay attention, you might put the whole thing back together not aligned correctly, then the lens might be attached in a 90 degree (or 180degree) off position. This happened to me in a +/- 90 degree position last night. I need to take it apart once more to place the M-mount correctly. But since the whole lens is turning it is a difficult endeavor and takes some patience and luck to catch the correct position in the first place. But nevertheless I did use the lens today and without any lens movements whatsoever. Quote Link to post Share on other sites More sharing options...
250swb Posted September 3, 2014 Share #10 Posted September 3, 2014 Just in case anybody mistakenly gets the impression it is a difficult job, as I said above, you don't need to take the lens apart, just loosen the flange screws and re-centre the flange.
