Hi to all.
I need to clean the aperture of Pancolar Zebra 50 F/1.8 M42. I have reached it from behind, but now I have problems removing front lens elements to get to the aperture. Can you, please, tell me, how can I remove the front of the lens to reach aperture assembly?
Currently I am this far:
Thank you for your help in advance. |

Thank you for your reply!. However, I can't get it apart. I have applied a significant force, but not enough. However, this pin looks like it may prevent the front part to unscrew. It's not a screw - ti looks like a pin. Please, let me know if the pin has nothing to do with unscrewing. In that case I will try even harder

I rest my case. I bought a tool for car oil filter replacement to unscrew the lens, no success. It's either the pin or something else... If anyone has any additional idea, I will be more than happy |

There are several versions. I think i have the same.
Take out the name plate, it unscrews seperate from the rest. I do this with rubber rings and matching tools to press the rubber on the ring for unscrewing. Underneath you'll find 3 screws, these take of a larger part. You now have access to the rings that hold the glass elements. From there it's easy!
It should look something like this: (just a quick shot to demonstrate)

Thank you all for your replies. I believe the lens I'm trying to clean was dropped some time ago. During trying to unscrew the name plate front lens element just fell out - I didn't unscrew anything. And because barrel is squished a bit it holds the nameplate very firmly.
If anyone needs any spares, let me know |
