Default Dust removal at start-up

I have a k10d that is set for dust removal at start-up. I turn the camera on and off alot. does this wear it out alot faster?

what do you all do with your setting related to dust removal?

Well, I have mine set to come on at start up also. I'm not sure what you call "a lot" but,
I don't think it will cause any undue harm. Although, like anything mechanical the more you use it, the more wear it gets, I can't see it being a problem.

Hi Bowenp,

I just use it when it's needed, and don't have it set to activate automatically. I really don't have too many problems with dust on the sensor though I change lenses frequently. I also found that multiple dust removal actuations (3-4) works better than just one, so have little faith that activation on startup would actually do the job if it was needed, but if it works for you, then there's no reason to change it.

I had it turned on for a long time, but then wondered the same thing and turned it off. I don't notice any difference about how often I've had to blow dust out. I do leave the K-7's turned on at start-up, but it's a different method of dust removal.

Mtngal, What does the K7 do instead of vibrating the sensor?


I only use the dust removal when needed. I justify this with the old 'if it aint broken, dont fix it,' saying. I had it turned on for a few days but just pictured the mechanism that holds in place, breaking from one too many shakes. I imagine the worst, I know.

To quite from pentaximaging (Pentax's US website):

Quote:
Dust-free image capture
The K-7’s Dust Reduction system, improved over previous K-series cameras, features a piezo-ceramic vibration action to the sensor’s low-pass filter for dust-free image capture.
So instead of shaking the sensor with the SR mechanism, it does something to the low-pass filter. It's much quieter and there's not so much vibration to the camera. I leave it on and never worry about it - rarely think about it any more.
