>Also can be stated: People underestimate the importance in megapixels. the difference between 16 and 24 is greater than you think.
I think in terms of resolution increases, not megapixels and I know exactly what the resolution increase is.
So in your example, the increase is far less than a lot of people estimate. D7000 at 4928 pixels on the long side vs D7100 at 6000 pixels is less than 21 percent larger, or at 240dpi print resolution, a native 20.53" vs a native 25". Same is true in the incremental increase from 24 to 36 mpixels in FX. The calculations in both cases are assuming a sensor of equivalent dimensions and not having to calculate crop factor.
People tend to think that there is a huge increase from 24 to 36 mpixels, but as you are probably well aware, it takes a geometric factor of 4 times the megapixels to double resolution. Everything else is incremental amounts. Personally, I don't want to deal with a 96 mpixel image.
