This lens features a fast f/1.8 constant maximum aperture that benefits working in difficult lighting environments throughout the zoom range and delivers increased control over focus when working with selective focus techniques. The optical design offers three F Low Dispersion (FLD) elements and four Special Low Dispersion (SLD) elements that reduce chromatic aberrations and colour fringing throughout the zoom range. One high-refractive index, high-dispersion glass element controls spherical aberrations for improved sharpness and clarity.
