From the official announcement:
April 2010 17-70MM F/2.8-4 DC MACRO OS HSM Wins EISA Award
The Sigma Corporation is pleased to announce that the 17-70MM F/2.8-4 DC MACRO OS HSM has won the TIPA Best Entry Level Lens award.
TIPA (Technical Image Press Association) is comprised of 31 publications from 12 countries. The knowledgeable chief editors and technical editors from these publications form the judging panel for the awards. Photo Imaging has been a prominent part of the TIPA awards since 1991.
This large aperture standard zoom lens includes an OS (Optical Stabiliser) function allowing the use of shutter speeds approximately 4 stops slower than would otherwise be possible. The maximum aperture of F2.8 produces an attractive background blur and improves autofocus speed. Three aspherical lenses and one ELD (Extraordinary Low Dispersion) glass element provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images. The incorporation of HSM (Hyper Sonic Motor) ensures a quiet and high speed AF.
This lens has a minimum focusing distance of 22cm (8.6 inches) throughout the entire zoom range and maximum magnification ratio of 1:2.7, making it ideal for close-up photography. It is possible to focus as close as approximately 4.7cm from the tip of the lens to the subject making this lens particularly useful for close-up photography.
The Sigma Corporation will continue the development of outstanding products that will answer the wide variety of needs of customers in the future.
