Can't wait to see sample images and sensitivity comparisons...
That's really interesting. A claimed advantage of medium format digital cameras have been that they have color-optimized CFAs rather than high ISO, it would be awesome if this sensor has taken the same type of optimization. Actually NO! The trend with MF is to optimize the ISO availability ;-)
I think a 50 megapixel camera for sure should be optimized at high resolution use cases, rather than trying to be a hand-held low light action camera.
A plea to the more knowledgeable people here:
Could you please enlighten me why Canon is going for colour that actually eye perception is UNABLE to differentiate? Or I misunderstood it?
I think you did not understand. A strong color filter allows saturated colors (as a bright red flower) be captured without loss of color depth. In this regard, the old 1DS Mark iii was well above the 5D Mark II, which supposedly would have the same sensor.
It turns out that 1DS Mark iii had images with depth of color much better at ISO100, and noise worse at ISO 3200. I believe that we will see something similar with the new 5DS.
