I have been using a certain other 12 MP camera long with my D2X this week, and an interesting revelation came out of it. At least for me. How well one can hand hold a particular field of view (a scene) is not about photosite size. It is about megapixels. The other camera has a photosite size of around 8.2um, while the D2X is 5.5um. But I am finding I can hand hold them for a given scene at pretty much the same exact shutter speeds. Of couse this means a shorter lens on the D2X than on the other camera. This has to be true, otherwise pocket cameras with 2.8um photosites would be impractical. But they are common. And I find I can hand hold a camera like the Sony P200 (7.2 MP) just fine at 1/30, which is about my limit for 30-50mm (35mm equivalent) views. For some reason I got it into my head that photosite size was literally the issue, but it isn't.
