I noticed recently that I have a cluster of about 9 pixels showing red. I contacted Nikon technical support who looked at some photos and confirmed they are 'hot' pixels and say I have to send the camera in for repair. My D300 is almost 5 years old so well out of warranty, and Nikon say they cannot give me even a ballpark figure that the repair will cost, although they will advise me of the cost before they do the repair.
Adobe Camera Raw automatically gets rid of the red dot the hot pixels cause, so I do not know if to send it in for repair or just live with it. Has anyone else got this problem? Any advice anyone can give me would be much appreciated.
