What we are seeing might be just advances in in-camera noise reduction software.
The ISO 102400 number might be useful to cause a (press) stir but I don't see it to become photographically relevant.
Do you agree that the image is such for the iso12400 samples I posted above, or are you talking about the iso 102400 samples posted in DPR. I think even the iso 12400 samples are not usable.
Just want to clarify....these 12400 samples looks like the K-7 iso 6400 samples with high NR downsized to ~6-7MP. 1 stop advantage there? I think the images are labeled wrong, as it can't be that bad. The iso 6400 looks sweeet, pretty much like iso 1600 or even 800 in the K-7, so that's a 2-3 stop advantage. But, FF needs cropping power with today's APS-C's having 15mp+ sensors, birders and wildlifers will demand croppability with their FF's, which they don't have. So, they really have to spend the dough on the 600mm, 800mm fast lenses. I am afraid Nikon dropped the ball here, and Canon is going to prove them wrong.....a 5DmkII with mk1 AF will make the Canon the sole leader in high end.
P.S: of course these are just my layman's opinion, I could be wrong......
