OK, can someone help me out here?
I'm pretty sure... I'm almost positive, that my K20D until recently did not display this, but after each shutter, it's making this kind of funky whining/scraping/vibrating/I don't know what to call it sounds. Better if you just listened to it:

I fire the shutter 4 times, the noise after the first one is the loudest, the noise occurs an instant after the shutter with the 2nd time, so it's hard to distinguish, but it's there, and then the 3rd and 4th shutters, you still hear the noise, but it's fainter.
Now, it might not sound like much in the audio file, but believe me, when I have my eye and face pressed against the camera, it's pretty annoyingly loud. Moreover, I think I sense a slight vibration that goes along with the sound, just behind the LCD. That's why I though it might be OIS related, but the sound doesn't go away when I turn OIS off.
Actually, the exact same thing happened to my K200D last year, and that time, I sent it to Pentax in Colorado, and they sent it back to me saying there's nothing wrong with it.
Except, when it came back, the sound was gone
I'd purchased my K20D in the mean time, so I immediately sold off the K200D so I don't know if it had truly been cured, though.
Anyway, it's back, and I'm just wondering if this just happens to all Pentax DSLRs after a while of use. Does anybody else have this problem? Am I just super unlucky to have it happen to me twice, two models in a row?
Just so you know, I have never dropped my K20D or bumped it hard etc., which was also true of the K200D when it developed this problem.
If it's just something that happens, and more importantly, if it won't develop into something more serious, I'm thinking of holding on to it for a while longer, perhaps till immediately before my warranty runs out to get it fixed for maximum efficiency.
Thanks for any help you can give me.
