Turns out my Yashica f2 lens has a nice case of fungus. Long thin stringy bits. Seems to be inside the rear element. Been doing some digging and I should be able to remove the group and clean it as its a press fit. Will take a look at it when I get home.

Edit-

scrap that idea. Got home and tried to undo the screws and they rounded off. Is usable but won't be coming off again. Will get a replacement lens.

Another edit- managed to "drill out" the offending screw. Fungus isn't too bad but I can't get the rear element off so it will have to do until I can find another lens. Managed to take a chunk out of my thumb in the process. Really need a dremel type thing.
