I would suggest that megapixels be the very last thing you look at. Any current Nikon or Canon DSLR has a megapixel rating at or beyond the point of diminishing returns. High megapixel ratings on phones or "point and shoot" cameras are a joke and represent nothing but a "horsepower race". If you have some good AI or AI-S Nikon lenses already, get a camera that will allow meter coupling with those lenses.
