Rob, Let's do this semi-scientifically (not difficult so don't worry) so we can make direct comparisons. If you have access to a Windows PC then you can run the little application "Dead Pixel Test" which is available for DL at http://www.starzen.com/imaging/deadpixeltest.htm which will provide a text report which can be saved for analysis. If we all test our cameras using ISO200 at 1/4000, 1/4 and 15 seconds with NR off and saved as TIFF we can directly compare results. Any statisticians amongst us up to the task?
