Sigma 10-20mm f/3.5 EX DC HSM Reviews

TechRadar reviews the Sigma 10-20mm f/3.5 EX DC HSM and writes;
“Considering the Sigma is one of the cheapest lenses of its type, it’s very well built, with a high-quality feel, impeccable finish and some neat touches, including the distance scale being positioned beneath a viewing window”
Rating: ★★★★☆ reviews the Sigma 10-20mm f/3.5 EX DC HSM and writes;
“Perhaps surprisingly – and unusually for an ultra-wide lens – we could find no evidence of vignetting at any focal length setting, even at f/3.5. Flare was generally well-controlled for such a wide-angle lens. “
Rating: ★★★★½

Popphoto reviews the Sigma 10-20mm f/3.5 EX DC HSM and writes;
“Sharp, with high contrast, it produced Excellent-range SQF numbers at every tested focal length, with distortion control that matched or beat that of the more expensive Nikon. And its control of vignetting was even better.”
rating: N/A

Ephotozine reviews the Sigma 10-20mm f/3.5 EX DC HSM and writes;
“Sigma’s latest 10-20mm is a very interesting lens indeed. The comparatively bright constant f/3.5 aperture make composing and confirming focus in low light conditions easier than with its slower predecessor, which will certainly help those shooting dimly-lit interiors and at night.”
Rating: ★★★★½

Lenstip reviews the Sigma 10-20mm f/3.5 EX DC HSM and writes;
“The MTF values recorded now place Sigma in the very lead of this equipment class. At the same time, we still have a very good build quality, very good autofocus and excellent work against bright light.”
rating: N/A reviews the Sigma 10-20mm f/3.5 EX DC HSM and writes;
“The new Sigma 10-20 mm f/3.5 EX DC HSM leaves us with mixed feelings. The build quality of the lens is certainly excellent, distortion is a little high at the wide end (but excellent for the rest of the zoom range), there’s also a fair amount of vignetting and CA, but that’s typical for this lens class.”

User Opinions

Sigma 10-20mm f/3.5 EX DC HSM User Reviews

Didn’t Believe It Til I Saw IT | Rating: ★★★★★
“All are great and I have three other Sigma lenses as well–none is as fun and accurate as this one. When time permits and budget allows, I’ll do a comparison of the Nikon 12-24 but let’s face it–it cost three times as much and is generally considered Nikon’s tour de force.” – by JJon Shaver

Best 10-2x lens I have used | Rating: ★★★★★
“Just picked up this lens on a Canon mount, and boy what a sweet lens. I find it to be just as sharp if not more so as the Canon version, yet costs much less. Focus is silent and fast (and spot on). Using my Canon 7D’s spot focus, the lens nails it every time, even in the edges at 10mm. I will be picking up another to keep in my back up bag.” – by Justin C. Sinks

A Fantastic Lens that Opens Up a Whole New World | Rating: ★★★★★
“The build quality on this lens is as good as any of my Nikon lenses. But what is really outstanding about the vocal range of this lens, is the way you’ll see the world through it. Take it to the beach during sunrise or to the mountains on a snowy day and you’ll see what I mean. The vista through the viewfinder is to die for. A lot of people have opted out for the 18-200+mm wide to long telephotos, thinking it’s the only lens they’ll ever need. Well, I challenge them to put this lens on their camera for a day. They will be surprised. “ – by Tiffany Ann

Love it | Rating: ★★★★★
“I’ve gotten into shooting time lapse with my Canon 7D. I got this lens because it seemed good and I figured it was time to take a chance on a sigma lens. So far, I haven’t been disappointed. Here’s a link to a time lapse I shot with it the day I got it. “ – by deezTx

Review – Sigma 10-20mm Canon mount | Rating: ★★★★★
“Superb condition, great result. Unlike other Sigma lenses in lower segment made for Canon cams, this one gives much superior colour production and detailing. Vignetting is minimal compared to others and distortion is pleasant. Flare is a bit of issue but tricky, one may handle it smarly. “ – by Urvish Joshi

Excellent ultra wide people still don’t know about. | Rating: ★★★★★
“The color reproduction is wonderful, and flare is controlled very well by design. The hood is ample, although when shooting wide the sun always seems to find its way into frame. “ – by Francisco Marquez

Features & Specifications

Sigma 10-20mm f/3.5 EX DC HSM Specifications

Sigma Corporation is pleased to announce the new Sigma 10-20mm F3.5 EX DC HSM. This super-wide angle lens has a maximum aperture of F3.5 throughout the entire zoom range. With its wide angle view from 102.4 degrees it can produce striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasize the subject. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 9.4 inches (24cm) 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 and polarizing filter. The Petal-type hood blocks extraneous light and reduces internal reflection.
