Just talked to Canon USA again. I was told that the camera is finished but they spent all day today fixing/calibrating it and it probably wasn't shipping out today, but tomorrow, so i won't have it back until friday.
I was told that the notes said the AF system had to be adjusted electronically.
So we'll see when i get it back. I have a feeling there are many more affected 7D ii's out in the world than just mine, and all of the microadjusting, the anti "microblurring" (this seems as mythical as the 100-400 being a dust pump) techniques in the world are not going to help.
To all of those having problems, despite what the internet says, it may not be you, it may be your camera.
I'll post back when I have the camera back.
