Hm, definitely interesting.
But if it's a 1D, it's the same amount of pixels, and maximum is ISO 51200? Or is that the highest, and then expansions like 102400?
If it's the 1Ds, it has less megapixels - makes no sense, Canon has and had the technology to put much more pixels and keep the performance great.
I'm guessing a 1D, though am a bit disappointed, was hoping for the 1Ds.
