The Sigma 17-50mm f/2.8 EX DC OS HSM Zoom Lens is an incredibly versatile, lightweight, and compact lens designed specifically for digital SLR cameras with APS-C size sensors. The lens has a fast f/2.8 maximum aperture throughout the entire zoom range. It features a construction of 17 elements in 13 groups with glass that corrects for flare, ghosting and all types of aberrations. It produces high contrast and sharp images throughout the zoom range even at its maximum aperture.

Sigma's OS (Optical Stabilization) feature allows you to shoot at shutter speeds approximately 4 stops slower than would otherwise be possible. This means your images will look sharper, even when shooting without a tripod in low existing light or at maximum range with a flash. This lens is also equipped with Sigma's Hyper-Sonic Motor (HSM) which provides for fast and quiet autofocusing.

The Sigma 17-50mm f/2.8 is ideal for many photo opportunities particularly landscapes and portraits, but with its wide focal range and a close focusing distance down to 11" (28cm) you can capture images with unique perspectives. It will quickly become one of the most important lenses in your gear bag.

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

This lens is for use with digital cameras with APS-C size sensors only. 1
The DC designation on the barrel means that this is a special lens designed so that the image circle matches the smaller size (APS-C) of the image sensor of your digital SLR. Its specialized design gives this lens the ideal properties for digital cameras, including a compact size and lightweight construction.
The 17-50mm f/2.8 offers Sigma's OS System (Optical Stabilization) that allows shooting at shutter speeds approximately 4 stops slower than would be otherwise possible, for sharper handheld photography even in low-light situations.
Constructed with 17 elements in 13 groups, it features FLD ("F" Low Dispersion) glass which is the highest level low dispersion glass available with extremely high light transmission. This glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. FLD glass offers superior optical performance, equal to fluorite, at an affordable price.
Its HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus.
Sigma lenses are made in Japan.

    I'm a simi-pro photographer. I have 39 years under my belt. I am using two Canon 40D mainly shooting wedding,family portraits and model shoots. I gently shook the Sigma 17-50mm prior to mounting it on my 40D, I heard the clicking sound as many of you've. The lens is light compared to the canon lens I use. I did have to get use to the focus ring rotating during auto focus, ensuring that my fingers was not in it way. I imediately took over 150 shots with my Sigma 17-50mm lens and all I could say is Wow, straight out the box. The pictures are amazing. They are all in focus and sharp colors, no purple fringes, sharp from f2.8 up to f16, no vin, and all 150 photos is a keeper. The rings all rotated with ease. The Sigma have a zoom lock that can only be lock in 17mm position but while unlock holding the canon 40d downward I never experience any lens creep. I notice a few complaints about the lens not being sharp while using a tripod. The instruction that came with the Sigma lens tell you to turn the OS off when using a tripod. I took some shots with OS on and some with it off. The shots were all keepers with the OS on however the Shots with the OS off gave the the big wow factor. Maybe I got lucky with the lens I receive, and I'm very impress with the Sigma 17-50mm F2.8 EX DC OS HSM Zoom Lens. This is my first time trying Sigma lens I'm quite happy that it worked out for me.

    Bought this lens from B&H 2/27/12. It takes great photos when the auto fucus works. I sent it to Sigma Service Center in July to have the AF problem fixed. It worked for a little while. Today,11/23/12 I sent it in again the AF just doesn't work. It will not lock on and if it does the photo is wayout of focus. I really liked this lens if it would work. I couldn't recommend this lens because of the AF problem.

    This is my second sigma 17/50, and I am disappointed with the sharpness, the first one which I had problem with, the barrel getting loose was repaired and it did affected the sharpness, reason why I bought an other one, this new one is not any better??? I will trade for Canon lenses.

    Comments about Sigma 17-50mm f/2.8 EX DC OS HSM Zoom Lens for Canon DSLRs with APS-C Sensors:

    I must say I am really impressed with this lens. This is my first pro-level lens. The focus is perfect 8/10 times. Its a very sharp lens, and gives good results in low-light. The background blur is okay. I have heard complains about this lens losing its focus, I hope they resolved the issue, and I really hope my copy will not have any trouble in the future.
    Overall, if you are on a budget, you will not be disappointed with this. Its a good alternative to Canon 17-50.

    I mainly shoot video with my DSLR but like to dabble in photography from time to time. This lens is very versatile with both video and pictures.

    I have taken this lens to the beach a couple times during golden hour and the picture quality was significantly better than the kit lens. It was also good at taking action shots of my dog playing on the beach as well.

    There are some lens flares when using the 2.8 at night, but other than that, this is a good daily-use lens for both photo and video!

      from Buffalo, NY

      Comments about Sigma 17-50mm f/2.8 EX DC OS HSM Zoom Lens for Canon DSLRs with APS-C Sensors:

      Couldn't be happier with the speed of this lens and the build quality for the price point. Only thing I would change on this lens is the size of the focus ring. It is very short and can make it tricky to pull focus while in movie mode.

        Comments about Sigma 17-50mm f/2.8 EX DC OS HSM Zoom Lens for Canon DSLRs with APS-C Sensors:

        I chose this lens as my first upgrade from the 18-55 kit lens that came with my Canon T3. After reading and watching every review I could find on this and other comparable lenses the Sigma pretty much was the clear choice on paper. After having it for awhile I know now I made the right decision. It is larger than the kit lens (see photo) but not to the point that I find it bothersome. The build quality is solid and the focus and zoom control rings move smoothly. The focus ring does move while auto focusing which means you have to watch how you hold the lens while shooting. Also there is no manual focus while in AF mode. These are mildly annoying shortcomings in light of the image quality for the price paid. Auto focus has been faster and quieter than the kit lens although it does have to hunt around a bit in low light. To be fair I'm not sure whether I should pin that on the lens or the camera body. All in all I have no regrets in buying this lens and recommending to any one looking for a good, moderately priced standard zoom.

        Nice lens, easy to use and sharp, but not much more than the Sigma 18-250 mm f/3.5-6.3 I already own and use on a Canon 60D. I bought if for the larger aperture anticipating better IQ but found that a Fujifilm X30 28-112 mm with an f/2-2.8 lens that I bought later for travel use handled the larger aperture situations just as well in my pixel-peeping tests using RAW+JPEG images and provided JPEG results SOOC extremely well. So this lens is being returned as I do not need it anymore.

                  Comments about Sigma 17-50mm f/2.8 EX DC OS HSM Zoom Lens for Canon DSLRs with APS-C Sensors:

                  Beautiful Lens, wish it were a bit wider. Also 2.8 isn't great, but does the job. All around great value.

                      I've had this lens a little over a month and it has been great on my 70D. Very sharp and fast in low light situations. Since I'm usually shooting at dusk and night this is a great advantage to me. The build quality is great, not overly heavy, and has become my goto lens for walking around and dusk photography. I would definitely recommend this lens to anybody wanting to upgrade their kit lens.

                        Too noisy as a video lens

                              I thought I had heard great things about this lens, but perhaps it was a different Sigma lens. This one was too noisy for use with my 70d for video. It's a nice range, but that was my primary reason for getting it. I didn't test it too much with video, but I'll wait for the next version from Sigma, or look into other offerings.
