Re: Canon EF 50mm f/1.2 L USM lens

Are you sure it's exactly in focus at that point on the chart?  That magenta fringing could pass for longitudinal chromatic aberration from a lens focussed just beyond the chart.  I know that when focussing on stars with some of my lenses they change from green-tinged to magenta tinged as the focus goes past infinity.  That lens will have a tiny depth of focus and it won't have the flat field that a macro lens has.
