k-5 startup sound

Just curious, but what's that sound the k-5 makes when you first start it up? What is it actually doing?

That is probably the sensor dust removal, it shakes the sensor to remove dust.

Really? I thought the dust removal was ultrasonic. Whenever I activate the dust removal mechanism in the options menu it's practically silent.

It is the sound of the aperture control motor cycling. K-7 does the same thing at power-up.
