Can you show us an example of when you needed the extra 2 or 3 stops? No really, I want to see. I have no clue what it looks like.
Constantly promoting specific Nikon products in a Canon forum might not be necessary, but I don't get the recent witchhunt for people wishing for more dynamic range ... of course it's useful in high contrast situations, even though even 2-3 stops more isn't enough to pull back all clipped highlights, but it sure would help.
Attached is some shot I recently wished for more dynamic range as it was a noon shot with clipped whites.
I thought shadows were meant to be black, doesn't it look fake if they're not?
If you really don't know the problem you're lucky and seem to be shooting completely different stuff to what I do. There's a difference between clipped shadows because of limited dr and deep shadows where *you* want them in postprocessing - or you should be happy with a mobile phone and half the dr of a current dslr because then images are destined to look natural, aren't they? No, of course not, +100 contrast is as unnatural as raising shadows until there is the distinct fake "hdr" look.
