A Line Across Autofocus Points


Hi all,
I was just wondering if anyone has experienced anything similar, or can explain what my problem might be. I bought a Canon EOS 300v with a twin lens kit - 25-90 and 90-300mm lenses - about 6 months ago. I hadn't noticed any problems with it. Just recently I've looked through the lens to see a small "hair"-like line across one of the autofocus points. It's hard to explain, and I'm probably lucky to have seen it, because it's quite fine and light. But now that I know it's there, it sticks out very badly. I've got a roll of film in my camera and not sure what to do.
Any help would be greatly appreciated. I love that camera and lucky enough it's still under warranty, but what are my chances of getting it repaired/ replaced???
Thanks :PP

  If the "hair" appears no matter which lens you use, then it's on the mirror or the focus screen above it and will not appear in the photos.

Do not touch the mirror or focus screen, and do not use lens cleaning solution or lens tissues on them. These are very fragile and are do not have protective coatings like the lens does. Besides being very easily scratched, the silvering on the mirror could be damaged.
Use a blower brush (not compressed air, which could damage the shutter curtains) to gently remove the hair.

  Check if the line moves when you move the autofocus area select. If that is the case, then, in my opinion, this line is the one along which contrast is maximized in order to achieve autofocus.
