K5 dust removal ...no noise...Broken?

The k5 makes no noise when I use the dust removal system. Can some of you with k5s test your cameras ? I am concerned that it is not working. The k7 made a noticable high pitched sound. The k5 has no sound.

Thanks,
Teri

As posted in a couple other threads, that appears to be normal. There is no noise when you operate the dust removal system on the K5.

Before I posted that as just an object of interest, I found by pressing my ear firmly against the K-5 body you CAN hear it, but damn its quiet compared to the K20 I came from.

Thank you for the information

Thank you. I was thinking the function did absolutely nothing. The k7 makes a short high pitched screeching sound when the dust removal system is operated, but maybe with the new sensor on the k5 the dust removal function is totally ultrasonic. If anyone does hear a sound created by their k5's sensor cleaner, please
let me know.

Thanks,
Teri

I did determine that the dust removal pulse does exist. I took off the lens, then I was able to hear a high pitched buzz when I activated the sensor's dust removal feature.

with the k-x and k20d you can feel the vibration very obviously.

Hopefully it's closer to the superior Olympus DR system.

I have the k7 and the k5. the k7 has a very noticable high pitched buzz when the dust removal system is started. I guess their is quite a bit of variability camera to camera.

It seems the K-7's DR system makes a soft, high-pitched whine when it operates.
My kid can hear it, but I can't..... I guess there's a "user age" factor in there somewhere
