Canon 28mm f3.5 fungus
I recently acquired a cheap canon 28mm f3.5 with the intention of trying out the focal length. It was cheap because it has some fungus. I really like using the lens I was thinking of having a crack at removing the fungus. I'm a complete newbie to DIY lens repairs but quite comfortable taking things apart and putting them back together. I've bought a lens wrench, but I'm not sure where to start on the lens. There seems to be two rings in the back with notches and a bunch of screws, what do each of them hold in place? Where should I start?
The other issue with the lens is the focus ring often unscrews, if anyone has any tips on how to tighten that up properly while I'm working on it, that would also be really helpful!
