Ive bought a D70 with my dad more than a year ago, and i think I found quite a big problem: There seems to be a scratch on the AA filter which is in front of the ccd.
Ive cleaned it a few times with a cloth for optical stuff, which Ive put around a q-tip and wanted to buy a more professional cleaning kit soon...
Does anyone know if theres some kind of fluid for this case (I dont know, but ive seen fluids like these for glass things in general before I think.), or how much Nikon takes if I would send them the camera for repair?

Are you sure it's a scratch and not merely a thin, determined smudge/streak? I'm not sure what Nikon's fees would entail in your case, but you could check out Visible Dust's website for some of their cleaning products, which include wet cleaning tools as well:¬*¬*http://www.visibledust.com¬* I've been using the sensor brush for nearly a year (perfect cleaning every time!), and more recently added their sensor clean solution in conjunction with their polyester swabs - very easy and effective, as well as gentle enough to preclude any excess pressure on the AA filter during cleaning.

I agree. The AA filter is incredibly tough. Unless you try to clean it with something metal, it wont scratch.

In addition, you can go to Nikons site and find "authorised repair" centers, probably one near you. For real problems, they ship to Nikon, but for minor stuff, or if you want a professional to clear your camera, they work just fine.

Hi,

When cleaning my D70 I also noticed what appeared to be a infinitesimal scratch. It is approximately 5mm up from the bottom and is perfectly straight across. It leaves no trace in any photo I have ever taken and I must conclude it is made that way. I can't imagine why it's there but if you hold the sensor in the light just so, you can see it. Invisible unless you've seen it before. Hey, if it doesn't affect anything, who cares.

thanks for the replies. I think I'll buy a brush from the site but since there seems to be no single 24mm brush and I dont want to buy the set for 100$ Im not shure what to do. I guess cleaning the whole sensor with an 8mm brush is a bad idea, right?
Does anyone have other recomendations?
