hello All, i have opened it up to check everything and ive noticed these marks on the lens, looks like scratches or kind of condensation inside the lens. Tried to remove it but it seems to be on the inside. Will this effect the quality of the image produced? Or should I find somewhere to go and get it sent off to be cleaned? and how much would I expect this to be? Also, I have the model that has the Berthiot on the ring, ive heard there are lots of 16 s.t.o.p models, is this one a good one? Or does it not matter? Thank you for anything
