I picked up two so I am covered with 70-200 and 200-70.

I am curious if you can post the raw files from the 2 cameras with the same setting, preferably same lens?
Anything other then guessing would require a better description or, better yet, sample files. But since the 5D3 has higher IQ then the 1D4 across the board, some good guesses include:
* You're viewing images at the same image viewer magnification (i.e. 50%) without realizing this actually magnifies the 5D3 image much more.
* Different in camera settings.
* Different RAW converter setting defaults or profiles.
And if you're not talking about a test pair produced under exact conditions (same subject, lighting, lens, exposure, etc) then anything and everything is in play including lenses, exposures, focusing, selected apertures and/or shutter speeds (beyond the obvious exposure differences), subject, lighting, etc, etc.
Because they would be stuck using a mobile platform so bad, that MS had to buy the only manufacturer who was still interested in using their flop.
I got the Canon versions for the same reason as Neuro, for use with my 600mm, but from what I hear and read, the Kenko will work just as well. Giving the short DOF, I strongly recommend a macro focusing slider and the best I have found is the Really Right Stuff. It is very high quality, very smooth. For really close ups I use the Novoflex bellow. But then your mobility become quite snailish.
If you add a 12mm macro extension tube it will work.
Just a reminder that the Canon teleconverters will not work with the macro lenses.
