yes, that remains but big change from D FA FA 100mm F2.8 Macro WR, D FA 100mm F2.8 Macro no WR, FA 100mm F2.8 Macro and F 100mm F2.8 Macro lenses is the optical formula of the new lens:

Quote:

[ the ] optical formula has also been redesigned to improve image quality compared to its predecessor. and now incorporates one ED (Extra-low Dispersion) glass optical element and two Anomalous Dispersion glass optical elements to compensate for various aberrations and minimize the generation of the unwanted purple fringe effect. The lens coating has been upgraded to HD, which significantly reduces average reflectance in the visible ray spectrum.
