Hello,

Does anybody know how to disassemble Sigma Widerama 3,5/18 YS-mount lens?
I've got one for my Exakta on Ebay recently, but during the inspection I've notice something that looks like fungus deep inside the lens. Seller "forgot to mention" that fact, but now it's too late to complain. So, the only way for me is to determine whether it is the fungus or not and, if yes, to try to clean the lens. To reach the damaged area I should disassemle the lens practically completely. Thus a manual will be very helpful to avoid the possible damage of the whole lens.
And please don't advice to send the lens to US or Europe repairmen, because the shipping costs will exceed the cost of the lens itself

Regards, Evgeny.
