This large aperture standard zoom lens offers an aperture of F2.8 at the 17mm focal length and is ideal for many situations such as portraits, sports, macro and general photography The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. The maximum aperture of F2.8 makes this lens ideal for hand held photography as well as producing an attractive background blur and high speed auto focus. This lens has a minimum focusing distance of 22cm (8.7..) throughout the entire zoom range and maximum magnification ratio of 1:2.7, making it ideal for close-up photography. It is possible to focus as close as approximately 4.7cm from the tip of the lens to the subject making this lens particularly useful for close-up photography. Three aspherical lenses and one ELD (Extraordinary Low Dispersion) glass element provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images. The incorporation of HSM (Hyper Sonic Motor) ensures a quiet and high speed AF. This lens has a rounded 7 blade diaphragm which creates an attractive blur to the out of focus areas of the image

I received the Sigma 17-70 2.8-4 OS HSM from Amazon five days ago. I have taken about 400 shots with this lens, including landscapes, indoor family gatherings with flash, and a sporting event in a large, well-lit indoor arena. It seems to me that this lens works as advertised. I don't see focus problems with this lens in either the AI Servo to AI Focus modes on my Canon XSi. The XSi exposure metering seems to work fine with the Sigma 17-70, and I cannot see anything wrong with color accuracy. The finish, appearance, and feel of the lens are pleasing. I like it, and it certainly seems to be a good value given its relatively low cost vs. function. I have awarded four stars in my rating only because of my limited experience with this lens. If this lens continues to work as it has so far, I would award a fifth star.Photography is my hobby, not my profession, but I carry my camera to work and shoot nearly every day. I cannot afford high-end camera equipment, so I make do with what I can afford. Even so, I have had rewarding successes and lots of fun with my hobby. My photos have been published in magazines, textbooks, brochures, large-format calendars, and web sites. They have been framed and hung on walls in office suites, sports arenas, and homes.I have used Sigma lens for the past ten years, and currently own four Sigma lens for my Canon XSi. Sigma lens are cheap, they are most often lightweight as compared to Canon lens, and they work acceptably well. I am familiar with the "you get what you pay for" concept, and I understand that sometimes there are issues with Sigma lens. I can see why professionals need sturdy equipment, but overall Sigma has provided me with a successful and cost-effective way to observe, record, and enjoy my surroundings.

I read several reviews of the Canon version of this lens that said it was common to get a copy that focuses inaccurately. I'm here to say I took the chance and got a good copy! Mine focuses perfectly, right where the camera's focus points light up. I'm using the lens on a T2i, which doesn't have focus microadjust, and they worked together right out of the box.Image quality is great. It is a touch soft at the wide aperture at longer focal lengths, but definitely still print worthy. Stopping down a bit sharpens it up nicely. f/2.8 at 17mm is really good, and the middle apertures are always excellent. Colors and contrast look fine to me, and flare seems well controlled. It has GREAT bokeh.HSM focuses quickly and pretty quietly. It does NOT have full-time manual. I think all of the audible noise comes from the sliding of the focus ring rather than the motor. Sometimes if the lens needs to drastically change the focus distance, it will hunt and there is some quiet chatter from the ring starting and stopping repeatedly. I wasn't sure how quiet it was supposed to be, but it's fantastic compared to the loud buzzing of the Canon 35mm f/2. The only absolute comparisons I can give are, it's much quieter than the shutter click, but still loud enough to hear in videos. Oh, and it's quieter than a Sigma 30mm f/1.4 I tried, which was quiet but sounded squeaky and rough.Macro is really fun. It can auto focus about 3 inches from the front of the lens at the wide end, and about 1 inch zoomed in. Manual focus can get just a little closer. It makes the lens very valuable as a walk-around lens to be able to take a landscape and then crouch down and fill the sensor with a flower.OS (optical stabilization) is a small benefit. It doesn't feel as useful as the IS on a little Canon a570IS that I have. I'd say it gives about 2 stops of benefit consistently. It's also not dependable with longer shutter speeds, like slower than 1/10. It helps but it won't make the image perfectly sharp. It seems more like it smoothens the image motion instead of locking it down. If you move the lens while half-pressed, then you have to wait a second for the OS to come to a stop. This is actually good for video though, as the lens motion stays smooth while panning instead of jumping from one stable position to another. The OS is barely audible in silence, quieter than the HSM, but it might get recorded by the built in mic.Build quality is great for the price. It's substantial but not uncomfortable, and a little front heavy on a Rebel. The rings are smooth enough for photography. Zooming is unusable with video because it takes some force to zoom and it will cause your camera to tilt unless you have it on a tripod. It's smooth and you can be precise with it, but it requires force. The benefit to that is that the zoom doesn't creep at all. It has a zoom lock but I never use it. The focus ring is light and easy to move, but not buttery smooth. It's sticky enough that it won't accidentally move. It doesn't have much travel though so it takes some finesse to get precise focus.All things considered, this lens performs above and beyond its price. It has so many features, I'm having trouble choosing my next lens. And to all Canon users: good copies exist!

I feel this lens turned out pretty good. After using it day and night for about two months these are my observations:Sharpness: Pretty good. IQ is best on average a couple stops down from wide open. Once you hit its sweet spots, the resolution is outstanding. Its sharpest setting is a close match to photos from my Tamron 90mm Di macro lens, although the Tamron is sharp across more of the frame and more apertures.Focus: Mine came with a very slight front focus bias, around 1mm. But its not that field relevant for me. Speed is quick and quiet. Seems to be consistent.Bokeh: Very Pleasing. I'm satisfied with the quality of out-of-focus blur, as it is smooth and renders highlights with nice round circles. Since the sharpest setting is a couple stops down from wide open, and the fact that its a multi-varying aperture, bokeh is not as "blurry" as I want it to be. I did notice a small amount of lateral chroma in the bokeh, slight purple and green fringing in front and back out-of-focus planes, but it did just as well as the Tamron macro lens. Overall, good but subtle results from the rounded 7 blades.Color: Good results. A little on the cool side. Contrast is good a couple stops from wide open.Focal Length: Outstanding. 27.2mm-112mm 35mm equavalent is nice for walk-around travel and portrait. Its 1:2.7 magnification ratio is nice for closeup photography like food shots.Optical Stablization: Works as inteded but I feel the image "pops" into stable position more abruptly than Canon OS. Both work well to about 3 stops.CA: Great results here. I find it handles this one well beyond 17mm. I think the 3x aspherical lens do help.Vignetting: About par with any good lens. Although there, its not a field issue for me on 17mm focal length.Flare: Great results. Handles sun shots well. I think the improved ELD glass helps. Comes with a feathered petal hood too.Distortion: About average. I think the kit lens was a tad more distorted. Geometry is easily corrected in Lightroom.Cosmetics: Awesome. This lens looks fierce on a small body. Gold accents and soft rubber-like texture give it class.Handling: Zoome creep is ok. Keeps its own when walking, but if I jump it will creep a little. Only time will tell if it gets worse. The zoom lock is in an easy to reach location.Overall, I would recommend this lens if you can't afford the Canon 15-85mm lens. But if I could save up the money, I would definity shoot for the latter.
