Sigma has announced the ultra-telephoto 50-500mm F4-6.3 EX DG/HSM lens, which is also optimized for digital SLRs. It has a new lens coating which reduces flare and ghost and also creates an optimum color balance. It also features HSM *Hyper Sonic Motor*which provides a quiet high speed AF function, a zoom lock switch and has four pieces of SLD (Special Low Dispersion) glass for correcting color aberration. It costs £899 and will fit SLRs with Sigma, Canon, Konica Minolta, Pentax and Nikon-D mounts.
