It doesn't seem that there will be a huge (if any) improvement on DR to compete with the SONY sensors. To me, that's a big disappointment that Nikon is sure to jump on with the D5.
No way to tell, until we can see what the floor noise is. That is the only place that the Sony sensor beats out Canon for the prior sensors. If they have fixed this, then Sony will no longer have an edge.
I would hope they wouldn't put this in their marketing unless they have indeed increased the SNR. However, that all being said, I suspect that the biggest change will be their firmware/software that cleans up raw noise before storing the raw (yes, I think they will have to do this before the raw storage, else we would be able to see the lack of progress otherwise). In the past, Canon has put quite a bit of effort into the code, from better NR algorithms to a better JPG engine.
With a standard range of ISO 100–51200, the EOS-1D X Mark IIis incredibly sensitive, and thanks to a high signal-to-noise ratio as well as powerful noise reduction, the EOS-1D X Mark II can shoot at expanded sensitivities down to ISO 50 (L) and up to 102400 (H1), 204800 (H2) and even 409600 (H3)!
This concerns me however, because they keep using the same reasons for lower noise each release, and if they had truly had a breakthrough in sensor tech, they would call it out. They don't however. There is nothing in this sentence that instills confidence in new sensor tech, IMO.
The EOS-1D X Mark IIcamera features a Canon-developed 20.2 Megapixel full-frame CMOS sensor that not only helps it record more pixels, but also includes gapless micro lenses for enhanced low-light performance. This results in noise reduction in dark portions of the image even at high ISO speeds,....
