Well here's a long shot...
I'm an audiovisual student studying in the Netherlands, and I recently acquired a pretty good Xenon 50/0.95, but the rear element is almost opaque due to fungus. I removed the fungus, but it had etched itself into the glass. I tried everything, but alas, it has etched itself so deep that it is unsalvageable.
Therefor I'm looking for a rear element of this lens, as the rest is in perfect condition. Just the last part of the lens, unscrews easily.
Do you have a busted lens? Do you have one of which everything's busted, but the glass is okay? I'm okay with some scratches or what not, everything's better then this 'groundglass' of a rear element!
Please let me know! Any help is gladly appreciated.
