A key and somewhat disappointing behavior seen here is forward focus shift (centering of the zone of focus moves substantially closer with stopping down). This behavior is discussed and shown on the Zeiss Otus 100mm f/1.4 Focus Shift page as well as in Painted Rock.
To obtain optimal results from the Zeiss Otus 100mm f/1.4 APO-Planar, it is essential to compensate for the focus shift in order to place the zone of sharpness ideally for the subject matter.
