Sigma 10-20 EX DC HSM review roundupThis lens is a winner of TIPA's best consumer lens in Europe 2006. 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 102.4-63.8 degrees (for Sigma mount) offers the photographer greater freedom of expression

MomentCorp reviewed Sigma 10-20 EX DC HSM and wrote:
"This is a pretty decent lens, with its best performance on 10mm, and pretty bad performance on 20 mm. I personally really dislike the EX finish, to me that gives me the feel of cheap optics. As you can see i find this lens to have more drawbacks then positives, that said the lens is usable, specially around 10mm, where it delivers weary straight lines, compared to how wide this lens is. If you enjoy taking IR photography, this is definitely not the lens for you."

Juan Parmenides reviewed Sigma 10-20 EX DC HSM and wrote:
"The distortion at 10mm is, surprisingly, almost nonexistent, allowing to photograph landscapes with almost right horizons, anyway, if we maintain the wide-angle photography doctrine inside its parameters. Starting at 14mm the lens shows pincushion distortion and it is more or less as its partners. The vignetting is the typical for this type of zooms and it is about around 1 EV in the worst cases, that is to say, at 10mm and f4, something that you can solve if we have Photoshop CS2, using: filter / distortion / lens correction, and we can fix vignetting easily."

2Point8 reviewed Sigma 10-20 EX DC HSM and wrote:
"For less than 500 euro you can’t get much better than this. The lens is both sharp and offers more than acceptable contrast and saturation. Chromatic aberration could be an issue for those who choose to shoot wide open most of the time. Stopping down will control CA somewhat. The same can be said about vignetting. Its professional build quality and compact size makes this lens a real winner. Be sure to replace the front and rear lens caps with Nikon original caps if you choose to buy this lens."

Press release:

Super wide-angle zoom lens designed exclusively for digital SLR cameras.
Sigma 10-20 EX DC HSM

This ultra-wide zoom lens has a wide angle of view from 102.4 - 63.8 degrees (when Sigma mount is used) and it is exclusive to digital SLR cameras. SLD glass elements effectively compensate color aberration. Aspherical lenses provide maximum correction for distortion and various aberrations; high image quality is displayed throughout the entire zoom range. The HSM equipped models makes fast AF speeds and quiet shooting a reality, and it is also capable of full-time manual focus. It has a minimum focusing distance of 9.4" (24cm) at all focal lengths. It is also equipped with an integral Petal-type hood to block out extraneous light.

Ultra-wide zoom lens
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 102.4-63.8 degrees (for Sigma mount) offers the photographer greater freedom of expression.

Most Appropriate Coating for Digital SLR Cameras
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.

The best possible correction of aberrations
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.

Inner focus system
This lens incorporates an internal focusing system, which eliminates front lens rotation allowing the use of a Petal-type Hood and also minimize fluctuation of aberration caused by focusing system.

HSM (Hyper Sonic Motor)
The HSM equipped models ensure a silent, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and Nikon-D mount lenses.

Minimum focusing distance of 9.4" (24cm) at all focal lengths
This lens has a minimum focusing distance of 9.4" (24cm) throughout the entire zoom range.

Sigma 10-20mm F4-5.6 EX DC HSM is awarded TIPA best consumer lens in Europe 2006
Sigma 10-20mm F4-5.6 EX DC HSM super wide-angle zoom lens, exclusively designed for digital SLR, wins "TIPA (Technical Image Press Association) best consumer lens in Europe, 2006" prize. Currently, 31 publications from 12 countries are members of TIPA (Technical Image Press Association) organization and chief editors and technical editors of these publications constitute this organization. Since 1991, TIPA has presented many awards in several sectors, including imaging. TIPA has stated that with a versatile range of wide-angle focal lengths, a good optical performance and a budget price, the Sigma 10-20mm is an excellent investment for owners of DSLRs with APS-C format sensors. Its sharpness remains constant throughout the zoom range, and its compact size makes it an ideal companion for shooting travel, landscapes or architectural photography.

* Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
