20D mirror and sensor cleaning
Sending my 20D to New Jersey to be cleaned. Anyone else have
experience w/this? I tried cleaning the mirror and sensor myself and got LOTS of dust off but there are still MANY specs that appear on my images. I'm just a LITTLE worried about sending my camera away. Just want some opinions on the safety of this process. Afterall, this IS my baby. :-) I guess I just want some validation that this is going to be okay. -- Chris |

20D mirror and sensor cleaning
I live 10 minutes away from the NJ center. Its full fledged Canon.
I had to take my lens (17-85) there for some white flakes that got stuck to the glass inside the unit. Amount....$0 since I dropped it off there. Was 1 year old so they were nice about it. I just recently cleaned my sensor with the ole pec pad and methanol. Took me 2 attempts between blowing out the coarse stuff and wiping the filter. Now its perfect. Cant find a spec at all on the pictures. If you change the lens OR you just like to take it off when you pack up your bag, you will have to sacrifice that practice for dust. I normally keep the one lens on at all times in attempts to keep the dust down to a minimum but since the lens itself is not a sealed unit, the pumping action of the zoom does and will allow dust to get to the sensor.

Are the chambers themselves airtight? If they are, I really don't see how pumping the zoom could put much dust in there; I'd think that the air escapes and is drawn in through the opening in the outer part of the lens. If the chamber is sealed, and the zooms have openings towards the chamber, you can change the pressure in the chamber a lot, I think, without actually transferring much air. -- John P Sheehy |

Like I said I DID get SOME specks off the mirror but there are still TOO many for me to go out and REALLY enjoy taking pictures. And I figure that now would be the best time to have it cleaned while there isn't too much opportunity for me to use it Jim Redelfs said: You're baby will be OK.

CHRIS REPLIES: Just shipped it today to New Jersey, to the authorized Canon dealer. I'll let you when when I have safely back in my hands. Thank you all for alleviating my fears. -- Chris |

20D mirror and sensor cleaning
FWIW the Canon tech that worked on my lens actually came to the counter and
explained how dust or specks could get into the lens chamber and up onto the actual glass itself. Not being the techo geek he was, it does make some sound sense in that when I zoom, I do it heavily and not that slowly. That can create just enough of a vacuum to pull something into the lens casing. Then if I continue to do that I could eventually push it towards the mirror assembly and possibly the sensor. That last part is something I doubt could really happen. Oddly also, I was NOT the 1st person that had brought in their lens with some white specks stuck to the 1st glass just behind the glass you can touch. Looked like dandruff to me. Perhaps the clean room where they assemble was not so clean that day... wrote in message ...
