REVIEWS (last updated: 16.10.06)

SLRgear reviewed the Sigma 10-20mm F4-5.6 EX DC HSM and wrote;
“Compared to the ultrawide zooms from the camera makers, the little Sigma holds up surprisingly well, particularly considering the huge cost disparity between them. Canon’s 10-22mm zoom tested very well, slightly edging out the Sigma 10-22mm in places, but getting beaten slightly in others. The Canon also does better in terms of maximum CA, but average CA is quite close to that of the Sigma. Likewise, the Canon lens does better with geometric distortion over most of its range. When it comes to shading though, it’s closer to a tossup, with the Sigma better at the shortest focal lengths, and the Canon better at longer ones….The bottom line seems to be that the Sigma 10-20mm f/4-5.6 EX DC HSM is a real bargain for an ultrawide zoom for sub-frame cameras. If you want to shoot really wide with your DSLR, this lens looks like a good way to go about it.”

Ephotozine reviewed the Sigma 10-20mm F4-5.6 EX DC HSM and wrote;
“With the wide field of view that this lens gives the digital SLR owners that require panoramic style angles, this lens is an answer to their prayers. The performance is excellent and the size and weight is little more than a standard zoom. Aimed at an area where there are no contenders stepping down from the 35mm arena and fulfilling a definite need, Sigma should be onto a winner here. In summary the main positive points of the Sigma 10-20mm f/4-5.6 EX DC are: Good performance, nudging excellent at the wide end, Ability to use standard filters, Weight, size, handling, & PriceNegative points are: Softish edges in middle of range, Slight pincushion at 20mm end.”

Press Release

Sigma Corporation is pleased to announce the launch of the new Sigma 10-20mm F4-5.6 EX DC HSM lens. The Sigma 10-20mm F4-5.6 EX DC HSM 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. Wide angle of view (102.4°at 10mm and 63.8°at 20mm) offers the photographer greater freedom of expression. Three SLD 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 Sigma EX DC HSM lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24cm ( 9.4” ) at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently.
