Sadly this does not fix it for me.
I have left side sensor issues, center and right module are dead on, but all left points are out.
For example on a 85mm f1.4G I need about +3 on the center and right, and -18 on the left.
I have tried the 11 vs 51 AF points, as well as other voodoo suggestions floating around the web, like
- disabling/enabling AF illumination
- locking the focus point after selection
- enabling AF point adjust but at 0
but none offer a true fix. This problem is hard to lock down because it is not always consistent. Almost intermittent on the 85mm f1.4s. I avoid the left points, but do test them from time to time, and sometimes they are dead on at f1.4, but usually way off. They are always way off on the 14-24 wide open.
I am transitioning to the AF-ON only method of focussing, which has been amazing, but sometimes I wonder if I am releasing a fraction of a second too early. But when I do test methodically and rule this out, gremlins are still in evidence.
Don't know when I can bear to give it up for a week to be repaired.
