MkIV Calibration Problems - A Stunning Resolution
I was reading a very long thread at naturescapes about various AF, microadjustments and calibration issues with the MkIV and 500/600 lenses described by several users and came upon the following post by Jan Wegener:

Apparently, custom MA settings might be interfering with the calibration protocol by Canon if they are not manually set to Zero before calibration. :eek: :confused:
Now, I have no way of telling if this is correct and I don't even own a MkIV but felt it might be worthwhile to let others know as many may give up reading that long thread.
Perhaps, Jan who is sometimes also posting here at BPN can provide a first hand summary of his experience.
