I don't know yet.  I noticed the ding when I unpacked the camera this
morning after my last trip.  I can definitly see it through the view
finder in air, when I cover the port with water I can't see it on the
port.

I ran it into some coral a couple weeks ago in hawaii after the camera
stoped working (I had clipped it off).  I went into a cave to look at some
harlequin shrimp (while I was low on gas) and then pranged it on a coral
head during the exit (I was low on gas and in a hurry to get out).

I'm afraid I have some coral in the lense, not just scratches.  After
polishing it out I can still see some faint hexagonal marks through
the viewfinder and I'm thinking about trying something more serious
than crest, but I've been told that flame polishing is necessary after
using real abrasives, hence the question.

After hearing the advice so far, I think I'll try shooting a cassette
next week.  Maybe it's just a deep scratch.  If the video doesn't come
out it's not a big deal anyway.

Thanks,
Scott.
