Sigma 10-20mm f/4-5.6 EX DC J 10-20mm
An ultrawide 10-20mm zoom with a constant f/4-5.6 aperture, it uses three aspherical and three SLD elements to fight distortion and color fringing, driven by a fast, quiet HSM autofocus motor with full-time manual override. Its internal focusing keeps the front element fixed, making polarizer use seamless and optical quality consistent at any distance. It suits budget-conscious landscape and architecture photographers who need a sharp, portable wide-angle lens for APS-C DSLRs.
