| p.1 #1 · p.1 #1 · Need help with Sekor C 90mm f/3.8 front element disassembly | |
I’m currently in the process of disassembling my 90mm lens for my Mamiya RB67 Pro S but in order to clean up what seems to be some sort of oil or grease spill on the outer circumference of the glass that has suddenly shown up in the internals of the front lens group, I need to open the small lens element up. So far I have been able to take the front plate off and the lens element out but I’ve now hit a road block trying to take the element apart in order to get in it. Anyone have any ideas on how to open this and clean it out? I’ve tried contacting every camera repair store where I live and there is only one guy who is willing to open it and clean it but he wants to charge me almost double of what I paid for the lens originally.
Here is are some links to a drive with some pictures for reference. Thanks!
