Hey just got my MF enlarging lens delivered this afternoon. A used componon-s 80mm, the lens is absolutely mint except on the bottom element inside it is slightly covered with tiny clear looking dots. You can see them if the lens is held directly to a light. Is this fungus? I'm thinking about having it professionally cleaned to remove these. I am also wondering should I learn how to clean lenses myself and what tools are required? I assume some device to unscrew the ring holding in the element? How risky is this assuming I only want to go 1 element deep and not take apart the entire lens?
Thanks
