Hmm, there's actually both purple and green fringing. I was waiting for this as a video and indoor family gathering lens but looks like I may revisit my other plan of picking up a used EFS 17-55. CA is just one of those things that makes me crazy.
For video: Scale these images down from 5760 px width to 1920 px width and look if the fringing (which is most probably CA) is still strongly visible.
For photography: use some CA removement tool (DPP does it).
But I understand that these deviations from reality make you crazy - I hope that the function to remove CA on the fly during video (if I read the info correctly the 5D mark III has it) trickles down to APS-C bodies ... and CA is just a minor issue in the future for ALL our lenses.
