Product Description
Sigma Corporation adds unique, anti-shake technology to award-winning 17-70mm lens Sigma announced the new Sigma 17-70mm F2.8-4 DC MACRO OS HSM. 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 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...

I didn't read too much reviews on this lens because it was new, but I heard relatively good reviews on the older model and with the addition of the HSM and optical stabilizer, it gave it more appeal. It is a great walk around lens. It has good range and the f2.8-4 is nice, but the 2.8 does disappear really quickly when zooming in from wide angle. It takes sharp photos from wide angle to zoom, and macro. The Body is well built with a solid construction. The focus and zoom rings feel good when rotating. The HSM is really quiet while auto focusing. The auto focus is a bit slow and sometimes has problems focusing during low light situations. Overall the lens works well and it gives me good results. Definitely a great replacement to the canon kit lens. 9 of 9 people found the following review helpful: ![]() By This review is from: Sigma 17-70mm f/2.8-4 DC Macro OS HSM Lens for Canon Mount Digital SLR Cameras (Electronics) I've had this lens for only a few days, but it's clearly a worthy successor to the old 17-70mm non-stabilized lens that it replaced. It is well built, both the AF and image stabilization work well, and is compact. The f:2.8 - 4.0 maximum aperture with the built in stabilization gives it a significant low light advantage. Images are very sharp. This is a great step up from the standard 18-55IS lens that comes on the camera, giving both better low light performance and greater range. I have a Canon 50D and checked the accuracy of the AF, and found that it was quite accurate - it does not front or back focus. |
