The clunking sound is from the internal stabilization function of the movable sensor, it is normal.

There are two types of auto focus lens for Pentax, the type you are using does not have a built in motor so the body drives the focus via a screw.

Lenses with built in motors will be quiet like your other brand.

Lenses with built in motors are called SDM, DC or HSM type lenses in Pentax mount.

Yes, Pentax cameras are not the quietest you'll ever hear, just get used to it

If it's any consolation, the screw drive mechanism may not be super quiet, but it is generally very reliable.

It's just the Shake Reduction, don't worry.

When you enable liveview you hear it probably even more.

The sensor is held on a sort of cradle which is moved up and down by the shake reduction. This is what you can hear moving, and it's totally normal - it has a bit of give in it until the shake reduction activates and holds the whole thing steady. The only time you'll not feel the clunk is in liveview when the SR is always active (if turned on!) Instead you'll hear the SR motor quietly grinding.

There may be two elements to the sound - (1) general sensor stabilisation (shake-reduction) at work while the camera is in use, and (2) shake reduction used to perform dust reduction/removal as a camera start-up and/or shutdown action (p 260 of the K-30 manual).

In all these cases you can turn off this behaviour, but there is no reason too. Shake reduction works well in normal camera use, and running the dust reduction feature at startup/shutdown is also useful.

Because the sensor is loose so the shake reduction keeps it in place but when you turn off the camera the SR turns off and it "drops" the sensor.

You can change the parameters so that the camera has no dust removal at startup or shut down, or one or the other, or both. I keep it at both, but default is neither (at least on mine it was).

Have fun with your camera

Also note that the shutter will make noises if you are using manual focus on a telephoto lens like the Tamron 90mm

Is that a new setting, with the older cameras you can only do it at start up?

First time hearing about that as well, you sure your camera is working correctly
