I just got my D80 today (from another Cafe member), and noticed that there's a bad pixel on the sensor. I noticed it in a regular shot right away, and it persisted on the image when I downloaded it to my PC. I tried several other shots, including one with the lens cap on for darkness. It came with the extended Best Buy warranty, and was bought about a year ago. Will I have any luck getting Best Buy to exchange it? (I checked, it is in stock) Or will I be stuck without a camera for a while, while it gets sent out?
