Does it look like stain issue?

Guys.. I have been using my Pentax K-5 for 3 months and never noticed any stain issues.. i did some tests when i first got it and was everything ok (most of my tests were done with a white-gray background).
However, i just came back from a trip and notice in 3 or 4 photos, only (out of 600) what could be stain, it looks pretty much like it.
What do you people say?
Dark background and long exposures might have spotted it

Unfortunately, that string of spots or pearls is most definitely the dreaded stain issue.

It's definitely the stain issue. Time to return the camera for a replacement.

Yes, it's the stains AKA the string of pearls.

BTW: It took me quite some time, too, until I first noticed them. They only come out in certain conditions.

I got a brand new replacement K5 from Pentax. Problem solved.

Cheers from Berlin,
