cant try it on another body in the shop?viggo do you have access to a 5D3 you can test it on?
mine is still amazing easily the most consistant and accurate AF 50mm i've ever used
its blazingly good in servo too (but i only use the 5 center column points using servo)
I have only the 1dx, but even with only center point with or without expansion points in any Servo or One shot mode it's the same results. I'm seriously considering a 35 L or 50 L AGAIN... At least the 50 L is pretty consistent and can be calibrated without wearing out the shutter with testing.
its wierd mine was so far off out of the box but after calibration its been fine, sure it misses now and then but definitely not anything as bad as the canon 50 f1.4. I wonder if your new body firmware messed it up? can you try roll back the 1Dx firmware to the old version when it was working ok to trouble shoot it?
