| p.1 #14 · What's this on an internal element? |
The spots are isolated on the surface of just one side of one element as far as I can tell, and that element seems to be right in the middle of the lens. Could it be residue or something that was part of the manufacturing process? I don't see how these spots could have gotten there, given their isolation, after the lens was put together. But what do I know, eh? The exterior of the lens seems to be as good as new minus a few scuffs here and there from normal usage. And functionally, it's perfect. Never had problems with the electronics, focus ring, or whatever.
