Dynamic Range -- what it is, what it's good for, and how much you 'need'

noise floor seems very important

to dynamic range

Certainly when you are pushing or pulling an exposure, I'll take all the dynamic range I can.

The biggest difference I see besides color accuracy between my full and m4/3rds is the ability to push or pull the exposure in post. There is very little room to do this on m4/3rds sensors.

I like DXO's noise floor cut-off on their dynamic range measurement. Puts some realism back into the measurement. The auto graduation feature to supposedly give more DR on Olympus cameras has, to me, only made the noise in the shadows to get that DR (seems like fake DR) not worth it.

On the other hand, in most cases, the exposure on my e5 is nailed not requiring much adjustment in post and I have enough DR.

When I do need more DR I'm typically switching to 7 stop HDR mode on my E5 which gets me more than I'd get on the Nikon anyway. Still that's one impressive sensor Nikon has.

E5 HDR shot (say's E30 but this was before Raw as supported so I tweaked exif)

and even more extreme

Neither of these would be possible as a single shot on any camera I'm aware of.
