I recently purchased a Sankor 16-D on eBay for my first anamorphic lens ever (yay!). However, upon receiving it I did notice a small amount of fungus on a couple of the inner elements. I'm not sure if it's affecting the image quality yet, I shot some test footage that wasn't very sharp but that could be due to it not being an Iscorama. Is it possible to take the lens apart and remove the fungus with a solvent or something? If so, how hard is it to accomplish?
