7D "sensor cleaning" sound - please check your camera

Can anyone who has 7D can check for this sound.
When I turn on camera I can hear "squeaking" noise twice.
When I perform "Sensor Cleaning/Clean Now" I hear the same sound 4 times.

I have two 40D cameras and they do not make this sound at all...

Can anyone collaborate on this...


To make things worst I found 1 dead pixel already... <= fixed (it was a stuck pixel after all, my bad - post #13 explains)

(copied from page 2)

I attached zip file with .m4a sound file for those interested.
I recorded it with my phone so please do not expect good quality

it is a sound of sensor cleaning option ("Sensor Cleaning/Clean Now")
You should hear 3 squeaks => mirror/shutter slap + 1 squeak => 1 squeak

For those who can hear it in their own cameras please let me know if this is similar sound...

I have not heard anything like that.

the same thing happens when i cleaned the 1d MK III. i think it is just the sound the camera makes, when you clean the sensor automatically. but i'm not really sure.

Only 17915903 left to go!

i would send back to canon asap. sorry dude. this is what all the "haters" warned us about.

You should hear no sounds because there is nothing mechanical about the process....

Told you so......just kidding...

squeaking would be the normal sound for sensor cleaning operation - my 1D3 sounds the same. I'm pretty sure the 40D had a sensor cleaning menu option, but this only flips the mirror up so you can access the sensor for cleaning yourself.
The 7D (and other models) has a "shake-the-filter" function that is supposed to shake dust off itself.

The dead pixel would be the thing that you should be more concerned with - this shouldn't be acceptable in a new camera. Send it back & request another one - don't let them con you into getting that one repaired.

I don't hear anything with mine.

Sheeesh, if I bought 18 million of something and found only one of those defective, I'd be delighted.

All good advice. The 40D has the "shake-the-filter" function as well. I think it uses ultrasonic vibrations? Maybe some people can hear them...

I hear it and heard it on the 40D as well -- seems normal to me.

To clear things out, that "dead pixel" turned out to be "stuck pixel".

Its gone after performing this technique:
1.keep the cap on
2.set your camera to manual sensor cleaning
3.keep it on for 10 to 20 sec.
4.turn it off

40D was one of the first Canon cameras with "shake-the-filter" function =>http://www.usa.canon.c​om …id=17779#ModelF​eaturesAct
That is the reason I found this noise new to me with 7D...

My 5DII made the squeaking noise when I first got it, but it went away pretty quick.
