Press Release: Sigma 10-20mm f/3.5 DC EX HSM lens

18 June 2009

 

Price announcement for the new 10-20mm F3.5 EX DC HSM Large aperture, super wide-angle lens for digital SLR cameras.

  • Ultra wide-angle of view with large maximum aperture of F3.5
  • Sharp images with high contrast and superior peripheral brightness
  • Super multi-layer lens coating reduces flare and ghosting
  • Aspherical lenses perfectly correct coma aberration
  • Hyper Sonic Motor (HSM) ensuring silent, high-speed AF

Sigma Imaging (UK) Ltd is pleased to announce that the suggested retail price of the new SIGMA 10-20mm F3.5 EX DC HSM will be £649.99. This new lens will run alongside the current Sigma 10-20mm f/4-5.6 EX DC HSM and is expected to be available in the UK in July for Sigma, Canon and Nikon fit, with Sony and Pentax fit arriving in August.

This super wide-angle lens has a maximum aperture of F3.5 throughout the entire zoon range. Its wide angle of view from 102.4 degrees produces striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasise the subject.

Two ELD (Extraordinary Low Dispersion) glass elements and one SLD (Special Low Dispersion) glass element provide excellent correction of colour aberrations. Four aspherical lenses provide correction for distortion and allow its compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting ensuring high image quality throughout the entire zoom range.

The incorporation of HSM (Hyper Sonic Motor) enables quiet and high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 24cm (9.4 inches) throughout the entire zoom range and a maximum magnification ratio of 1:6.6.

The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood. The, included, Petal-type hood blocks extraneous light and reduce internal reflection.
