Seems that there's a lot of confusion (at least with some) about what DR (dynamic range) is and what it's good for. This purpose of this thread is to get this cleared up.

I'd like to begin with a rather stark example of what 13.7 stops of DR (D7000) offers over 11.2 stops of DR (5D2):

That really is a good example of some of the advantages of what wider DR allows.

Striking, isn't it?

I don’t have the D7000 or any cameras with that sensor and I am happy to stick with mFT as a back up to my FF kit.

Absolutely. DR isn't the only measure of a system, after all.

I had seen the DR scores of the D7000 but must admit I was a bit sceptical about the result in reality. It makes one wonder what the next generation of FF cameras will be capable of.

I imagine that, at best, the DR will be the same, but likely still a little less -- that Sony Exmor sensor is rather amazing, and, so far as I know, Sony isn't making it in FF size.

16 x 2.25 = 36
14+log2(sqrt(3)) = 14.8

In any event, contrary to "common wisdom", DR is not a function of sensor size (or pixel size).

still, jim might be thinking of replacing his d3
