Cleaning a Carl Zeiss Jena Flektogon auto MC 35mm/F2.4 lens

Hello!

I would like to clean my CZJ Flektogon auto MC 35mm/F2.4 lens. I came across this link:

http://www.kolumbus.fi/uusilehto/img/le … ss/disass/

But i am unable to proceed beyond Step 4.

After removing the 3 screws holding the aperture-lens assembly, the assembly refuses to come out as indicated by the guide.

I also note that my lens is different from the lens mentioned in the guide...mine is 'auto' and the example above is an 'electric'.

Has anyone dismantled this particular lens? I would appreciate some assistance-guidance on the same!

Thanks!

P.s: The above guide applies perfectly to the Carl Zeiss Jena Pancolar electric MC 50mm/F1.8. I am having some problems with this lens and so dismantled it according to this guide with no problems whatsoever! Sadly, my problem is not rectified.

I got to know from the Manual Focus forum that there are different versions of the Flektogon 35mm/F2.4.

Mine has a minute screw on the barrel...which you get to see if you rotate the focus mechanism towards minimum focussing distance.

Now i am supposed to loosen this screw and unscrew the front element assembly...and then all will proceed as mentioned in the above mentioned guide.

I dont intent to take apart the aperture assembly as its working like it should. (I have also been warned that its quite a task to put it back together!)

I intent to clean the optics and re-assemble the lens. So now i will try out whats been suggested and i will post my results here!

Thanks and stay well.
