r/CanonFD

I can find a FD 300/4 for a few bucks, but the rear lens has fungus. According to the seller the other elements are fine. I've never taken a lens apart, how difficult is it?

Shot all of these handheld just after I got the lens for 120 Euros, really smooth focus ring, but focusing in itself is a bit tricky and the RAWs need quite a bit of post-processing but I am all-in-all very pleased with the results.
