thank you very much for the tip, I will perform this test as soon as I get back from holiday. When using a Pentax K5 with tripod and AF focusing; the result will be unsymetrical and somewaht blurres images on edges(not the eges of the frame) of the target object. Probably a good idea to test the 18-135 zoom at 31mm focal length too?

In the dead center the edges should be perfectly symmetrical regardless of the lens.
You can, of course, check the 18-135 but this is independent from the 31 in any case (unless we are talking about a camera defect).
Remember to switch off SR for the procedure.
