Voigtlander Vito CSR Fungus
Maybe somebody can help me.
A friend has given me a Voigtlander Vito CSR but the lens have fungus.
I tried to disassemble to clean it. I've been able to remove the front lens but I'm not able to unscrew the middle one. I attach a photo to show where I'm stuck.
Should I unscrew the three red (sealed) screws?
Should I turn the black outer tub of the lens counterclockwise with a special tooling? This black outer tub have a small hole but I tried to turn it and also with a rubber (homemade) cylinder without success...
Can anybody explain me how to continue?
I hope that somebody can help me.
