Dirty Sensor ???

Howdy All.
Dunno if anybody can help or explain. I seem to get dirt/dirt marks on pictures taken on a K5 regardless of what lens I use, when its stopped down to say f16 or smaller. If I perform the dust alert procedure, nothing shows up. Tried pixel mapping to no avail. Could it be a sensor fault?
Any reply greatly recieved.

Thanks in advance.

Most likely just dust on the sensor. Get a blower, lock up the mirror and see if that helps. Otherwise you may need to do a traditional cleaning or have the sensor professionally cleaned.

If you're still in doubt as to whether or not it's dust, please post a sample

Don't worry, it is almost certainly dust on the sensor. Buy a rocket blower, go into the menu of the camera, search for screen lock up in dust cleaning menu, then remove the lens and blow some air on the sensor being careful to don't touch anything inside the camera (eg sensor or mirror) with the rocket blower. Mount again the lens, turn off and on the camera. You should be fine.

Thanks for the replies. After I posted this some links popped up explaining some issues with this particular problem. Should have searched before posting I suppose. Looks like people have sent their K5's away to be cleaned but not fixed the problem. Think I'll not stop down so much and if I do, accept the fact I'll have to do some healing.
Thanks again.

Sometimes the dust alert function does not detect the dust (based on my previous experiences). Use a strong light with the mirror up if that's the case.

No point accepting limitations on how you can use the camera. Post a sample image so we can help you figure it out.

It can be dust on the sensor, but could be also dust on the back element of the lens. Check this too.

What do you mean live with it? Clean it , it is nothing but a thing. No seriously use a blower if not then get a sensor gel stick.
