good question. To make better portraits. I thought that it would be better than 70-200 f/2.8 L is ii usm with better f/1.2 option but I can see that I can not use f/1.2 every time due to lack of sharpness and focusing problems at f/1.2
I suspect that what you're experiencing is not a sharpness or focus problem, but the inherent challenge of shooting at f1.2 @85m without IS. Extremely shallow DOF....for tightly framed shots, even the slightest movement in the time between the AF lock and the release of the shutter will throw your subject out of focus.

135 would've been a good option, getting a full portrait at f/1.2 would be pretty hard. Sometimes every shot just cant have bokeh
Depends on the look you’re going for….they’re not really interchangeable, IMO. Longer focal lengths compress the background elements to an indiscernible blur.
Wider focal lengths like 85, 50, and 35 keep more of the background elements in the frame, but with a wide aperture, are still able to isolate the subject. Creates a sense context, dimension, and pop that you don't get when you blur the background elements completely out of the frame.
