The benefit of an aspherical lens is its ability to correct distortion and spherical aberration to ensure high image quality.
One aspherical lens can achieve the same level of performance as multiple spherical lenses. Therefore the size of the overall lens unit can be reduced by the inclusion of a single aspherical lens.
Dedicated aspherical lenses have been introduced to the XF lens system to maintain compact design and high image quality.
All Fujinon XF glass lenses are manufactured using highly precise molds and precision tools. Combined with the HT-EBC coating technology, the lenses can significantly reduce flare and ghosting.
