Thanks for your hat info, I think I will get one for sure.

Ok, thanks for the imput. I since I could not feel it on the newer camera, I was not sure.
Just now peering at the sensor under the mirror when I first turn the camera on, it looks like it may shake slightly, but I am not for sure.
But if you k3 owners say it is the same with yours, that is good enough four me!
Can't wait to learn all the secrets of this camera, it is a pity that magic lantern publications stopped doing books about Pentax cameras, the one on the k20d was outstanding, and was a constant reference guide.

Hi.
I just purchased a k3 recently. It was to upgrade my trusty k20d, that I have used for a few years now. One of the things that has fascinated me about the k3 is how quiet and dampened the k3 shutter is, it almost reminds me of one of my old bronica ETR leaf shutters.
But one thing I have noticed, compared to my k20d, is the sensor shake function. On my k20d when you activate it, you can hear and feel the sensor shaking in there.
So I was very surprised when I hear or felt nothing when I activated that function on the k3. Do you think it may be a malfunction, or is the sensor just dampened so well on this camera that it is almost silent? When I got the camera, it only had about 3,000 shutter firings on it, and everything else seemed to work great, and still looks brand new. Can any k3 owners out there cast any light on this? Thanks!
