Originally posted by creative69 Holding the camera in my hand and moving from say portrait to landscape you can hear the sensor mount or whatever sliding towards the side you tilt it. As I said very worrying to someone new to Pentax if fact it maybe be new to everyone because as you said a bigger sensor requires bigger mounts therefore bigger noise. As someone said knowing that simply removing the camera from the bag each time I pick it up slightly concerns me, surely that is causing wear and tear on something? To clarify something is sliding that comes to a stop with an audible clunk yes, doing the above movements with the shutter half pressed stops the movement and therefore the clunk.
I understand your concern, I had the same thoughts when I bought my first Pentax (the K10d). Here I had this supposedly rugged camera, and it felt like something was broken inside from the very first day. But as proven by thousands of Pentax bodies since 2006 the sliding sensor is not a problem.
It only moves a few mm, even though it feels as it moves a lot more than that.

Originally posted by Giklab The same happens on my K-5II. The sensor needs a moment to "boot up" so to speak, so as soon as you half press it gets moved into the correct position - it can't really do that in the split second it takes for the shutter to open, it needs to be countering shake before that to be effective.
Actually I don’t think is does need more than a few ms to move into place, since you can press the shutter button fully without half pressing and the sensor is lifted into position and the picture is taken without delay (well, there is always a delay, but you know what I mean). You just don’t get shake reduction if you fully press immediately.
