By the way like the other guys here I have different fine tune requirements depending on light.

In daylight my sigma 35mm 1.4 need -12.  In tungsten it needs -20

In daylight my 85mm 1.8 needs -7.  In tungsten it need -12

Did you check that after the firmware update.  It appears to be fixed.  I checked with my 85mm last night and the focus drift, under incandescent was completely gone!
