differences in color between Mark ii and Mark iii?

[K-amps]

I was wondering if the OP has 2 issues, one with saturation as a whole (outside pic) but is it possible that his headshot magenta / yellow tinge has something to do with CFL lighting? I ahve seen color shifts in te 5d3 under some CFL lights, I am sure other bodies will have their own behavioral issues...

Good news, Canon just announced yet another firmware update only days after their last one!

Firmware Version 1.1.3 incorporates the following improvements and fixes.

1. Fixes a phenomenon where being in the proximity of the camera and an Internet-enabled device may cause the user to complain.
2. Fixes an Internet phenomenon where exposure metering may change when using the top LCD light in underground crypts or tombs.  Under these circumstances, the camera will now simply play a sad violin song through the monaural speaker and shut off for 3 minutes.
3. Reduces the Nikon D800's DxO score to 62.
4. All picture profiles are fully updated and now personally approved by Ken Rockwell for their increased vividness.
5. New interactive menu screen that lets you choose why you are returning your camera before shipping it back to us.

Ha! Made me laugh. But you forgot one...

6. Adds metal spikes to the grip so no one complains about the camera not being sharp enough.

I thought they were both a similar shade of black plastic
