But Canon must respond to the D800/E and a7R. Canon must respond because (1) the 5DIII outsold the D800, and the a7R isn't really competitive in the relative sales numbers, and (2) Nikon responded by trying to boost sales with an incremental update and Sony responded by releasing a model with 1/3 the resolution. So everyone can see why Canon must deliver a high resolution sensor, right?!?
I wonder if it would be possible to make the 1DX2 as a 60 megapixel camera and run it in "crop mode" where it uses the central part of the sensor for reach, "full mode" for those monstrously large files, and "bin mode" where a 2X2 bin would give you a 15Mpixel camera with good low light performance, or even a 3X3 bin mode for a 7Mpixel camera with really good low light performance. ?
I think they need to take advantage of the fact that the amount of information you get from each pixel effectively decreases as the pixel density increases. Most of the photo won't have high-resolution components with any real intensity, so it ought to be possible to come up with a hybrid compression scheme that reflects this reality and nets you lots of compression losslessly. I'm just not sure what that compression scheme would look like.
