My k-30 have problem?

mengazaa · 08-25-2012, 03:55 AM

I just bought K-30 wth FA 77 f1.8 from internet. First time for me to use pentax
I have two question
1. I hear like a something move inside camera when I move camera (horizotal<---> vertical). Is it normal sound?
2. Focus sound is quite noisy compare with nikon or cannon that i used before. Is it normal?

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.

mengazaa · 08-25-2012, 05:27 AM

For my first question, I also can heard this sound when I turn off camera.

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

When you enable liveview you hear it probably even more.

mengazaa · 08-25-2012, 05:49 AM

I trun off shake reduction but I still hear

loco · 08-25-2012, 06:01 AM

It is normal!!!!!!!!

ihasa · 08-25-2012, 06:02 AM

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.

rawr · 08-25-2012, 06:04 AM

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.

Everything is normal dont worry , be happy
IT's probably the question that newbies at Pentax ask the most

mengazaa · 08-25-2012, 07:22 PM

thank you very much for all answers.

TJWest · 08-26-2012, 02:02 AM

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
