I state here again, Pentax Hong Kong recognize that is not the dust problem. This is the cmos problem. There are 6 same cmos cases in Hong Kong.
Now, Pentax Hong Kong promise to exchange a brand new K-5 to my friend in these 2 days. They will fully check the new K-5 again before sending to my friend.
I love Pentax, I do not have this cmos problem in my K-5 & K-7.
I just want to share some bad possibility in cmos and remind the worldwide
K-5 owners check their cmos carefully according this problem.
I even don't know if this problem only occur in Hong Kong or somewhere else.
I do not understand why some people have a bad reaction here.
These guys must be a die hard fans of Pentax
If your K-5 does not has such problem, that's very good.
Keep on enjoy your K-5. That's it!
