Re: The 1D and CCD
From what it looks like, the 1D's CCD is basically a larger version of the D1H imager. Rob's article alludes to this, and the specs make them look similar (same pixel size, 200iso base, etc.). Not sure if there was ever any official source, but I have heard from various different places that the Nikon imager is made by Sony.
However, remember that there is a lot more to the image quality than the imager chip itself. Amplifiers, ADCs as well as all of the other processing and interconnection stages involved in the chain. If the imager is in fact similar to the D1H chip, the basic image quality should be very similar to the Nikon - however both the imager and the other stages have several months on the D1H which should give them marginally better performance.
As for the dust problem, with a cell size the same as the D1H it won't be any worse than the H. The D1X has a more apparent dust problem because its pixels are half the size of the H cells. It also has to do funky interpolation, so the dust particles could be amplified.
However, being 4 megapixels one always has the choice to downsample to ~3mp and average out the noise while still having more resolution than the D1H. Either way, this camera should give us a good sample of both companies relative capabilities in digital camera design with a common central component [img]images/icons/smile.gif[/img]
