dust or what in *istD L

Hi
I've lately got some crap in my pictures and can't figure where the problem is. I've tried to clean mirror and sensor several times with Eclipse liquid and sensor swabs, with no success. Where else those could be? Same problem with all objects so the problem is in the camera.
On the right side a bit under center line. Two spots and "hair".
With aperture 22 crap is seen clearly, with av3,5 all the crap disappears?

It's dust on the sensor.. You don't have the built in dust shaker (that works marginally well anyway) but the rest of this would apply..

Thanks Jeff. I tried to use air blower gently with no success. Then I decided that whatta heck and used my air compressor (gently of course) and the hair is gone. Black dots are still there

Firstly do not try to clean the mirror. It is very easy to put permanent marks on it.

When it comes to the sensor you should be able to get it clean with wet swabs. Make sure that you move the swab across the sensor once and either take a new or turn it around before you do the next swab. Do not move the swab back and forth.

I have had my DL for 3 years and have cleaned it 3 times during that time. It works well every time.

I used to clean my K100Ds often with a Giotto Rocket Blower. It seems I can't change a lens without picking up a spot or two in the blue skys. Only once did I have to use a wet wipe.

The *istDs and K100Ds are cheap enough you can have a few on hand to reduce lens changing. I have a Macro camera and Tamron Super Zoom camera that have not had a lens change in a year. I have K100D Super (bought on Market Place!) that I use for interchangeable lenses since it has dust shake.

In spite of people who wrote me that a Super Zoom sucks in dust, I stopped cleaning the day I stopped removing it!
