Hi,
My take is that DR-wise the new 5Ds is going to be like a 5DIII, or better. It would be feasible that it could be a new generation of sensor having column-wise on sensor ADCs, we don't know until the sensor has been analysed.
Anyway, anyone who is happy with 7D or the 5DIII will be happy with the 5Ds.
The DR advantage of the Sony sensor is limited to low ISO.
As you know, existing Canon cameras are good enough to make competition winning images. Doubling the pixel count won't change that, but will offer some benefits.
I know two persons who shoot both Nikon and Canon, BTW, and I got the impression that they see the benefits of resolution and DR but they still really like shooting with the Canons. With the 5Ds the resolution advantage will become history, with DR we have to see.
Best regards
Erik
The sensor in these cameras is a new Canon CMOS fabricated sensor.
Based on what Canon has said in the past you can expect improved colour fidelity. Personally, I am doubtful you will see an increase in DR that matches the Exmor.
We need to wait and see how it tests and performs. Until then its just throwing darts at a board.
Amazing how many naysayers have large collections of darts though ![Grin ;D](https://forum.luminous-landscape.com/Smileys/default/grin.gif)
