Hello, I had a nasty scratch on my uwl-09 and polished it out quite successfully following the techniques discussed in this forum.
Problem is, although the scratches are gone, I appear to have gone through the coating of the dome (polished area actually looks clearer and brighter). The description of the lens says it has a “scratch resistant hard coating” on the dome, and “anti-reflection coating” on the lens.
Question is, does the dome coating actually have any optical properties? Or purely for scratch resistance? Reason I’m asking is I’m thinking of taking it all off altogether if it doesn’t do anything to improve image quality.
