Hi all,
I just finished blowing dust off of my K100D with a rocket blower, and now the camera is making an odd sound. It's a sort of low, static-y grumbling sound. It's not very loud, you need to be within maybe 6 inches of the camera to hear it. Honestly, it sounds a bit like a hard disk writing, but I can't imagine there's anything like that going on in there.
The photos from the camera seem to be fine as far as I can tell.
I've tried it with two different lenses and the sound happens in both cases. The lenses themselves seem to be fine with snappy aperture blades, smooth zooming & focusing. I don't get the sound when stopping down with the optical DOF preview.
I hear the sound for the entire length of a long exposure. If noise reduction is on I can hear it for about the same amount of time after the exposure. If noise reduction is off it bursts a bit after the exposure is done and then stops.
I hear the sound for the entire time that the camera is in cleaning mode, which I wouldn't think is processor intensive. But perhaps it's because the camera is displaying instructions on the LCD?
I do not hear the sound when looking through photos in playback mode.
Based on the symptoms I would guess it's processor or image-capture related somehow, but I can't figure it out.
Unfortunately this camera is going on vacation tomorrow morning. I'd really like to have some idea what's going on before then. Can anyone help me shed light on this, please?
Thanks in advance,
BKR
UPDATE: I turned off shake reduction, and then I don't hear the sound during an exposure but I do hear it during the noise reduction period after the exposure. So I guess maybe I managed to screw up something in the shake reduction system. Great.
From an academic standpoint it's interesting because that implies that shake reduction is turned on during the noise reduction period regardless of the camera setting. It also implies that it's on while sensor cleaning is happening, which seems really counterintuitive to me.
I'd still appreciate anyone's thoughts on this.
