PRESS SUMMARY |
 Sigma Corporation is pleased to announce the launch of the new 10-20mm F4-5.6 EX DC lens for Konica Minolta and Pentax digital SLR cameras. This exclusively designed zoom lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras. It covers a super wide angle of view 109.4 degree to 70.5 degree and has a wide-angle perspective throughout the zoom range. The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance through the entire zoom range.
Three SLD (Special Low Dispersion) glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.
This lens incorporates an internal focusing system, which provides high speed AF performance as well as a minimum focusing distance of 24cm (9.4in.) throughout the entire zoom range. It is also equipped with a Petal-type hood to block out extraneous light.
