Aspherical lens and SLD (Special-Low-Dispersion)This lens uses one aspherical lens and three SLD (the special low dispersion) glasses for excellent correction of chromatic aberration. Colour aberration in the secondary spectrum is compensated by using three pieces of Special Low-Dispersion glass (SLD), and making high-quality images a reality throughout the entire zoom range.
