One of the reasons that Canon 5D has such great picture quality is because of its huge pixels (8.2 micron). Shouldn't then Nikon D40 come close which has a pixel size of 7.9 microns? Or may be it already does? I have been doing a lot of search on google for this but didn't find anything relevant. Thanks! PS - Both of these cameras came out at almost the same time so the sensor technology should be comparable.
