I have to admit I only shoot Canon and this is probably pointless but I wanted so say it anyway. I also have a 1DX and love it. I am a wedding photographer and all of my favorite photographers love Nikon and talk about how awesome their D4s cameras are. I read in reviews that the D4s beats the 1Dx hands down. The 1DX loses to Nikon by 7 points in a sensor test on the DOX website. After reading about them I have a couple of observations.
The 1DX has more MPs
The 1Dx has a higher fps
The 1Dx has a better viewfinder
The 1DX has a better, faster, more accurate AF system
Now the D4s is supposedly better in all areas related to the sensor, especially DR, but here are some quotes from DOX website, "As for the much-vaunted dynamic range the Nikon D4s has an extra 1.5 stops at base over the Canon EOS-1D X but that advantage is eroded at higher ISOs and there’s nothing in it by ISO 1600....The Nikon D4S sensor may have a wider dynamic range and better color discrimination than the Canon EOS-1D X but the gulf between the two sensors is less than you might think, and that’s certainly the case with noise levels....The upshot is the Nikon has better low-light performance overall, but even then it’s really only a slight advantage when using raw, and may not be visible at all with out-of-camera Jpegs...the Nikon D4s is ahead of the Canon EOS 1D X, but in reality the two are closely matched and that applies as much to the technical spec’ as anything else... in the right hands both cameras produce results that would be difficult to tell apart.
So the D4s is a "better" camera because of the sensor, which is, in all reality, so little better that most won't be able to tell the difference, but it doesn't get any credit for better AF, more MP and a higher frame rate? Also it is 2 years older than the D4s.
