I picked up this lens at an Estate sale and on first inspection it looked great. I looked at it more closely and found a very small spot of fungus on the inside of the large front lens. I don’t think it will effect operation. You can judge for yourself in the photos. It has a small L37c 39mm filter on the bayonet end. The focus ring moves smoothly in and out...
