Tonight I noticed a pinpoint circular dull spot in the front coating. I think it is in the original coating, and I am not sure if it is on the inside or outside of the dome. It is small, and from most angles it is not visible, but from the right viewing angle it is obvious, though small. It does not clean off, so I think it is in the coating. I realize this will influence how most consider the lens, so I wanted to mention it. Sorry I didn't notice it before.
