New here... & K7 inquiry...

Picked up a K7 last week and upon arriving home, where it's quieter than the store, I immediately noticed the brief grinding-like noise upon startup. Concerned about the sound, I posted this in dpreview and the noise is apparently from the aperture actuator in the body *it was not the high pitch whine of the dust removal feature in case anyone is wondering*.
Indeed after inspection the actuator/lever vibrates up & down causing this oddity when the camera is first turned on.

Anybody else notice this?

I became interested in the K7 while searching for a compact and quiet (shutter-mirror assembly) DSLR. Read as much "initial impression" threads as I could and the muted shutter sound was a commonly mentioned virtue of the new body.
Had to check it out of course...
...lo & behold... I once again owe Visa...

The camera thus far has been great (note though that it's only been a few days) for my particular uses. Leaps ahead of my old K10D and, again noting that it's been only a short amount of time, *almost* on par with the D300.

But man, this startup noise is something to get used to... what would be the reason for this I'm wondering?

I have the K-7, the GX20 and the K10. They all make a sound on startup. The K10 & the GX20 have a sort of vibrating or light thumping sound. The K-7 is a kind of high-fregquency beep or squeal unlike the k10 & the gx20. It is however, the pivoting sensor doing it's dust removal vibration on startup. I was prepared for this as some other early users had described it early on.

As for the "acutuator/lever" (I assume you are talking the power on lever) vibrating up and down????? I don't think that falls under the "normal" category. I don't think anything is supposed to vibrate up and down on the camera. I would take it to a dealer or repair shop and let them witness the phoenomena you describe; but I don't think it is supposed to do that.
