when this lens, came out there was a lot of chatter about the focus shift and then Ziess offered a fix for it free of charge, I sent mine in, don't remember what the side effects were from the fix
I don't think they "fixed" the focus shift; they just changed the calibration point; I think early versions were calibrated for f1.5 and later versions (which is what I have) were calibrated for f2. Calibrating for wide open (1.5) produced severe back focus at f2 to f4. Calibrating for f2 is a better compromise, but this lens still has plenty of focus shift.
