What focal point are you using when shooting the 85L at 1.2 its pretty sharp are you using center focal point ? The octabox shot in the field with background tree came out sharp.
For the first photo, it was shot at f/2.0 using the upper-right focal point. Ever since moving to the 5DIII, I've been able to rely on other AF points than the center. If I would have used center and then dragged, it probably would have been fine at that distance, but I try to stay away from that technique.
In the second (wider) photo with the octobox, it was shot at 1.4. Because of the greater distance between the couple and the background, it worked out well. I hardly ever dip into the 1.2 range as CA and sharpness is noticeably hurt.
