For a start, at least the AFS 14-24mm f2.8 & AFS 24-70mm f2.8
Both featured for the first time, aspherical lenses including large-diameter PGM (Precision Glass Molding) elements to reduce coma and other types of aberration even at the widest aperture.
Not forgetting the Nano Crystal Coat; an extra-low refractive index coating that virtually eliminates internal lens element reflections across a wide range of wavelengths, and is particularly effective in reducing ghosting and flare.

exactly which lenses did they redesign for fx?
