Hello,

I bought a CZJ Sonnar 135mm f/3,5 and it looks good but aperture is totally suck. There is one blade misaligned but no oil mark.

I disassembled another CZJ Sonnar 135 3.5 and I wasn't able to repare the aperture because of a very tiny spring which was impossible to keep at the right place... until I lost the spring.

Hope I can fix the lens without disassembling everything.

Thank you for your help !

I dismantled the mount and got rid of the misalignment but the aperture does not work and the aperture pin is loose...

Can somebody help me please ?
