I have a 17-55 f/2.8 IS that is perfect except for a scratch on the front glass. It is small, so small I thought it was dust when I bought it. It doesn't affect photos in any way that I can tell, and I've looked. It sits just a little less than 1/4" from the outside edge of the glass.
Can it be fixed? Reasonably? I wanted to sell the lens but couldn't when I realized the "dust" wasn't dust at all but this scratch. So, should I get it fixed or take my loss and sell it "As Is"?
I bought it to use for a friend's wedding ($880) and put a UV filter on it as soon as it came out of the box, and off I went to the wedding. 2 days later, 800 photos in the can and only then noticed and tried to clean the single speck of dust I saw under the filter. That was when I found that it was not dust but the evil scratch.
What should I do?
