Glass with anomalous partial dispersion (elements 2/3) was used to ensure correct color rendition. Lens element 2 is made of a fluorite-type glass while lens element 3 is made from glass originating from the former Leitz glass laboratory. Lens element 4 has an aspherical surface. Lens elements 1?? 6 and 7 are made of glass with a very high refractive index to minimize monochromatic aberrations. In all every innovation currently available in lens technology - aspherical lenses?? glass with anomalous partial dispersion (APO)?? glass with a high refraction index and a floating element - has been combined to create a lens that will set new imagi
