My experience is that the 5D4 and 1Dx have very similar low light performance in terms of IQ but the focusing system is better in the 1Dx
Thanks for the reply!

Yes I have seem the DX0 mark ratings, I was hoping for some real life examples. I haven't found too many yet :-(

I would really rather stay away from the 30MP files, as they really will just take up more space, and aren't really needed. I keep leaning toward the 1DX2 for the ISO enhancements and the focusing system for low light.
