Scroll down to the Blue Sky shots and you\'ll see the mazing just like what has been posted on this thread - green channel imbalance is apparently a common and known occurence in many cameras from many manufacturers (it is regularly discussed on the Raw Therapee forum, and never about the 7D! )
It\'s so pervasive in fact, that you can\'t help but wonder if it\'s designed in...
Much of the non 7D discussion about it indicates that better demosaicing algorithms are the solution. Even Adobe is aware of, and considers that it is able to address, artifacts caused by the imbalance: http://forums.adobe.com/message/2321414?tstart=0
As post 7 there says:
Anyway, this simply indicates that there is a bug in Lightroom/ACR. It should not do this as it can clearly deal with unequal green response, and similar problems were fixed for other cameras with unequal green response.
For clarity, I\'m not saying that nothing is going on with the 7D, but I am saying that it appears neither to be unique to the 7D nor - on the face of it - terribly intimidating to providers of conversion software...
