I wanted buy new D7000.
As on some forums I red about video hot spots problem I wanted to be sure if it was only firmware problem. Response is NO. The sensor is completely crap. I checked 3 different, new, cameras in 3 different shops and results were the same. There were dozens of dead or hot pixels, majority red.
Test conditions:
Manual setting, ISO 6400, Speed 1 second, cover on lens - image normally should be completely black
Image taken in the same condition with my old cameras : max 2 pixels
