But back to the topic at hand: it's great to know about advances in technology, & how they may help us achieve our vision. DXO's quantitation, to an extent, helps some of us do that.
Cheers.
Sorry if this has been discussed in the thread on previous posts...
We all know Nikons use of the Sony Exmor produce fantastic DR, even if I personally don't put so much weight into it (as many other seem to do).
However as I understand it, the Canon sensors have the upper hand at long exposure times, perhaps if you have both Cameras, some nice Milky way pictures sure would be nice to see.
(Reasonable exposures would be like ISO 1600 f/1.4 8s at 35mm or with some star trails f/2.8 @ 32s)
I haven't seen if longer exposures actually gives better result in the Canon, but I've heard that was the Achilles heal on the Exmor sensors and that they would produce quite a bit of noise.
DR or not my Canon 5D Mark II is fantastic (at least on the center AF)
