24 MP from an entry level DSLR

I don't doubt for a minute that the photographer can be and often is a lot more important than the number of megapixels. I've taken great shots at 12mp and people who insist they HAVE to have 24 or 36 mp and probably don't need them anyhow are misguided.

That however does not change the fact that moving from 8 to 12, or 12 to 18mp, does provide a significant difference in resolution and ability to crop, as I proved in my other post.

Did Ken Rockwell come up with that 'how to calculate the difference of resolution' method that you used? It's laughably simplistic - and wrong.
