Is there any sugestions or tips to check if body or lens are working fine? Heard that some flaws are subject of exact camera or lens.
We have stupid laws that don't let return photo goods if they are "good". This folows from old film times. So I don't have second chace to change it.

Antanas,
I guess it is VERY hard to see if the camera works properly in the shop without bringing all kinds of test facilities, computer etceteras and work with it for some time.
The best thing is to agree with your supplier to be able to bring back the camera with a week, including all packaging, for no real argument.
Then you've gotten yourself a week to test.
I guess 99,9% of all cameras and lenses work perfectly well (there some doubt this is the case for the DA* 16-50mm lenses), so good chance you will be fine.
The possible issues you may come across are (as far as I can remember, don't own a K20D myself):
- High ISO banding in dark regions. This seems to be body specific, you'd need to replace the body as a whole.
- Viewfinder not aligned (tilted) with the sensor. Easy to test.
- Back / front focusing issues. The K20D should be able to compensate, but there are still problems reported if I remember right.
- You need to check if the lens is sharp in all corners. Not so easy to do since you need to fing a subject that is completely in parallel with the camera.
I hope this helps.
Most of the issues are not Pentax specific by the way.
Cheers, Bert
