Originally posted by kasv Kx and K7 are obviously heavily affected, K20D less.
Does the problem exist? Yes, I have seen it with my own eyes on my own K-x.
Do I believe it is widespread, or that the cameras are "heavily affected"? No, I do not. I have seen enough evidence from other cameras to know that rumors have blown it out of proportion, despite having the problem myself. Just like many of the so called "pandemics" of recent years, a few dozen people contract it, and the media makes it seem like millions.
As for your question, yes I have done some tests for it (I plan to do more thorough ones later), and no I have not seen it on my K-5.
