Only thing I have found is what looks like a hot green pixel in the same spot in all my photos.
You're fine on the stains issue, forget about it and enjoy the camera.
Unfortunately, hot pixels are a fact of life in this world and this is not considered a defect. Meaning, they won't replace a camera for that reason alone. Fortunately, the K5 has a built-in pixel mapping feature to deal with this issue. I've never used it so I can't give you any insight, but it's in your manual. If you shoot in raw, though, your raw converter will eliminate them automatically. I think I've had at least one on every body I've had, though, ironically, I haven't noticed one on my K5 yet. All mine have been red, though. Don't think I've even seen a green one before. Someone else have any insight on this?
Anyway, congrats on your new camera. Now go have fun.
