1) Doesn't make any sense to buy a camera with a known file size then complain about it
2) I'm coming from a camera with 165MB raw files. The D800 is a breeze. I know it;s all relative but really, the D800 file size is easy to handle.
3) So many captures is simply unnecessary unless the scene has enormous DR
4) Please, please stop using the term HDR when you mean tone mapping
