The 17-70mm F2.8-4 DC Macro HSM OS was the first lens released in the 'Contemporary' category of Sigma’s lineup. Designed to be an ideal all-purpose lens for APS-C sized sensors, the Sigma 17-70mm F2.8-4 covers an effective focal range of 25-105mm. This standard zoom is also equipped with a Hyper Sonic Motor (HSM) and an Optical Stabilizer (OS). The construction of the 17-70mm comprises 16 elements of 14 groups, including two FLD glass elements which Sigma says have performance equal to fluorite, with one SLD (super low dispersion) element to reduce color aberrations. The 17-70mm F2.8-4 Macro DC HSM OS is compatible with the Sigma USB dock, which allows some aspects of its feature set to be customized by the user.

Sigma's latest 'C' badged 17-70mm F2.8-4 is an excellent upgrade option for SLR shooters who've outgrown their kit zooms, and are looking for better image quality and more creative flexibility. It offers a fine balance of zoom range and maximum aperture, while still being highly portable. Autofocus and image stabilisation both work well, but image quality at wideangle isn't the best.
Photographers looking for a high quality, general purpose zoom for everyday shooting.
Not So Good For
Wideangle or close-up shots
I have been very pleased with the performance of this lens. I've put it through paces with indoor and outdoor use and the images are sharp and crisp. So far, no problems and I'm quite pleased with the quality of images produced with my 7D and the lens.
Very good allround lens for travel and general purpose
Sigma have done a commendable job on this lens. I am using it with my D5200. It is very consistent throughout the focal length and aperture range, i.e. good results wide open to f16 at all angles. Center sharpness is excellent with a little fall off towards the corners, which are still mostly good to very good except at the wide end where there is a more noticeable decline (from 17-35mm). Still better than all wide-angle zooms I have tried at that angle though. The shorter zoom range compared ...
Initial Impressions Sigma 17-70mm f2.8-4 "C" on Sony a77
I just got this lens so this is an early set of impressions... Note this is the Sony Version so there is no OS on lens. Pros: (1) I like the look. Clean monotone no bright color logos or even text reminds me of my old Sigma 24-135 FF I had years go, but smaller. (2) Every test I have seen says this thing is insanely sharp to the edged.
Super versatile, quality instrument
(1) Pros: well built, versatile, sharp at all focals/apertures, nice bokeh, spot-on focusing, price (2) no full time manual focus override, field curvature @ wide angle Bought it for our holiday. Having previously owned an original 17-70mm, I can safely say that this one is much better in every category plus a bit brighter at the long ...

Repair my Lens or buy a new one?
I have a 40D with 17-85 USM lens. The lens is playing up now with hunting and not being able to focus. The question, should I repair it or purchase a Sigma 17-70 2.8/4 DC? What is the view/opinion here please? Thank you in advance. Regards.

One of the failure points that is well documented is the AF ribbon breaking. My guess here. The question, should I repair it or purchase a Sigma 17-70 2.8/4 DC? At $500, the Sigma 17-70 is a bargain. It will eat the 17-85 for breakfast and poop out its back-cap. Great optics, size and macro capabilities (such as they are) to boot. At $580 (price at adorama/B&H) the 17-50 is mind-numbingly good with fixed aperture but without the range of the former. Figure possibly half that (tops) for a repair - but you won't know until you send it in. This is the part in the movie where the person faced with the terminally ill loved one: a) works 2 shifts and sells the engagement ring their grandmother gave them to hire a gifted surgeon to perform a miracle or b) takes a pillow and quietly smothers them putting them out of their misery and goes off to live ...

Sigma 17-70mm f2.8-4 OS HSM C vs Canon 17-40mm f4 L USM
Hi Everyone, Can anyone advice me which one should I buy, I will be using the lens for event photography, group and tight shots, and some landscape. We all know that Canon 'L' lens are superb in terms of quality, but the features / qualities of the new Sigma is pretty attractive, it is a new model, wide aperture up to f2.8, optically stabilized, and most of all, better price. What about the widest focal point of both lenses, as per the specs, Canon is showing wider angle of view than Sigma at it's widest focal point, 17mm. Cheers, Pidong Marcos
I choose the Sigma 17-70 f2.8-4 OS HSM C lens for the extra 30mm and 2.8 on the wide end. Don't know which it the sharper but I really like and have had no problems with it. I use it for events at Taylor County Extension office mainly. The Canon 17-40mm just isn't long enough in many cases. Continue Reading
I just wish someone would make a 15 or 17-85 f2.8-4 with stablization. I had a Canon 15-85 and loved it but it was just to slow for events but I really miss the 85mm. The extra 15mm helped in the size rooms I usually work. Continue Reading
The Sigma is a crop-sensor, APS-C, lens, whereas the 17-40L is a full-frame lens. The L lens is designed to be a good wide-angle, almost ultra-wide, lens on FF cameras, whereas the Sigma is a good all-around lens that extends from wide angle to tele. The L lens is really a bit short to be an all-around lens, but the shortness at the long end is not a fatal flaw (you can always crop shots taken at the long end). The L lens has superb build quality, the Sigma has decent build quality. The L is slightly longer, but surprisingly, the Sigma weights more. The Sigma extends when zooming--I dislike this feature--the L does not. The movement is all enclosed. The L has very good IQ on crop-sensor cameras, but it isn't excellent. The Sigma is very close to the L lens. The main differences are that the Sigma has more distortion and greater vignetting. For me, unless I planned to move up to full-frame soon I'd pick the Sigma. On an APS-C camera, I'd pick the Sigma 17-50 2.8 (a lovely lens ... Continue Reading
