Got a fd135mm F/3.5 for nothing. It is in fantastic condition apart from a thin fungs patch on the front element. I've never tried to do this before and have no pro gear. Can i get at this front element using things around the house like rubber bandsand plastic caps etc. any tips most welcom. Not too bothered about the lens but would rather not damage it.
Thanks

Yes, there are lots of ways of doing this without special tools. I don't know this lens myself so it's not easy to give accurate advice right now. Can you post a pic? What is the filter diameter?

The FD breechlock 135mm f3.5 is a good lens (on a film camera)..why don't you take some shots and if you are happy with them forget the fungus, just keep the lens in a dry place and it wont get worse.

Thank you for the advice guys, this lens is in such good condition apart from this slight fungus that I think I will take your advice and leave it. |

Better to learn repair using already throw-away lens -- you may fix it! 135 (and 50) are easiest imho.
