I shoot macro shots all the time with the FA 50mm and FA 100mm. The FA 100mm will exhibit some chromatic aberration on high contrast subjects, including minor purple fringing, wide open. Almost all of the CA goes away by stopping down one stop to F4. Note that the CA is visible only on high contrast targets wide open; most photos don't show it.
Also, get rid of the UV filter. You certainly don't need it, especially with the 100mm D-FA.
Finally, just as tip, it really helps if you don't strip out the EXIF data from your posted photos; if you do then we have to ask a bunch of basic questions (like what f-stop you are using) rather than you giving us all the info that we need in the photo.
BTW, your color profile for some of these images as listed as "Color LCD" which should not be the case. You should make sure that anything you upload for viewing on the web (as opposed to an ICC-compliant program) is converted to sRGB color-space.
