As nice as the new sensor sounds, the question is asked – Who needs a %$%#@ 50MP sensor anyway? In fact there are ongoing discussions currently on many web forums (including this site’s) on this very topic. It almost seems as if there’s a backlash underway against such a high resolution chip.
I find this hard to understand, but there may be two factors at work. The first is from within the DSLR crowd. 50MP is so far beyond what is now available in a 35mm format camera, and likely will always be so given the price, that there may be a bit of sour grapes at work.
