Pentax issued this statement about the stains on the Pentax K-5 sensor:
“To PENTAX K-5 Digital SLR Camera Users
We would like to express our heartfelt appreciation for your patronage of PENTAX products.We deeply regret that the first shipment of our PENTAX K-5 digital SLR camera included some products with a stained image sensor — a problem which we believe was caused during manufacturing – causing them to occasionally produce images with spots which look something like water drops, and which users cannot remove with ordinary cleaning methods.
