Removing rear group from Super-Multi-Coated Takumar 50mm 1.4

Hello guys, I have dissassembled and cleaned (remove oil from blades) from Super-Takumar 50mm 1.4 succesfully, but now I am trying to clean fungus from Super-Multi-Coated Takumar 50mm 1.4

I see that the rear group in this SMC is different to how to remove in Super-Takumar.

I put a few photos for if any of you could help me..

Unscrewing this ring I can remove the rear and middle lens from rear group.


The next one shows I say:


The problem is: how to remove the front lens from rear group?


For the other side I see three little screws, but I am afraid to remove this to avoid broke the diaphragm.



Any suggestion?

Thank you very much!

Add other view from the rear group.

It can see the third glass (I need remove this) and one metal ring, but it has not notches to permit remove it.



Thanks

Hi Arjay Bee, I asked about Super-Multi-Coated Takumar 50mm 1.4. With Super-Takumar there is no problem because the rear group can be unscrewed without problem, but no in S-M-C Takumar.

Thanks

I have bought other lens part diaphgram S-M-C Takumar from ebay seller and I asked him, the answer him and your answer have help me I finally a minutes ago I have removed the diaphgram succesfully and now I have got access to the front lens of the rear group.

The tip was, remove the three little screws that hold the diaphgram and (it is the key) push the diaphragm from back, then it outs of a piece! and then the fron lens can be removed.

I will try to take photos all proccess.

Thanks to all!

Hi again - yeah I know that was what you were asking but I was so tired last night I put up a link to the ST to stop anyone else doing it. I was as stuck with the SMC as you were - will have to do the strip down just as you have for the same reason - fungus tendrils everywhere.
Would appreciate any pics you can post for this repair.
