[QUOTE="spb_stan, post: 655184, member: 43545"] All sensors have hot pixels but are mapped out at the factory so they are not seen in either RAW or JPG. If a pixel fails after leaving the factory, it can be mapped out at any Nikon service center. Many brands allow you to map out hot or dead pixels but Nikon does not. With any device with 10s of millions of semiconductor elements like transistors, a few are bad so provisions are made to improve yields by being about to burn lookup tables to ignore that defective cells or transistors. Memory chips would be much more expensive if each had to be 100% functional. But mapping out those defective transistors from the addressing tables, the chip is still perfectly usable. Same with hard drives and SSD drives and camera sensors. [/QUOTE]
