For the camera have anti-shake function in the camera body, this lens's Hybrid Optical Stabilizer provide not only anti-shake function for the camera body compensation, but also provide the function to compensate the image shaking in the view finder of the camera like anti-shake compensation built in the lens. Incorporating four Special Low Dispersion glass elements and three Aspherical lens elements provides excellent image quality throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7 inches) at all focal lengths and a maximum magnification of 1: 3.4 reproduction ratio, making it ideal for close-up photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters and the supplied petal-type hood. Incorporating super multi layer coating reduce the ghost in the backlight photography.

Customer Reviews


I just recently bought this lens primarily for its Optical Stabilization technology.
My past lens the Sigma 28-300 was a great all around lens but it didn't have the image stabilization that this lens does. This lens with the range of 18-250 actually works better for an all around lens. I was a bit skeptical about the OS (IS Canon) technology but after using a Canon 70-200 2.8 IS. I couldn't go back to my sigma 28-300 without OS. I mean the difference was and is well worth the extra cost. I zoomed in all the way with the OS and without the OS on a rusted mailbox. The OS showed all the rust particles, the Non-OS showed blurred particles. That convinced me it was worth it. That extra crispness makes all the difference. Also, the price for this lens was outstanding when compared to the closest competition. I didn't really want the Tamron, and I wasn't about to pay 2,300 for the Canon 28-300 IS 3.5-5.6 that's nuts. Closer to 1,000 I might have. But this lens as far as I can tell is just as good as the Canon for a lot less expensive. I have NEVER and I repeat never had a problem with my previous Sigma lens. I had the 28-300 for about 3 or more years. And the image quality was always right up there with my Canon lens. I work with a 24-70 2.8L and a 70-200 2.8L IS, as well has 16-35 2.8L, my sigma photo quality kept up with if not is equal to them. Though the L series are built very heavy duty and are really great lens all around. The image quality is not all that superior if any. With the OS on this new lens the only advantage to a L series Canon would be the better build and better dust and weather resistance. But by all means the Sigma 18-250 is a all around winner for anyone wanted an all around lens.

Bought this lens as I can not imagine myself carrying two lenses and changing lenses in dusty outdoors. I was comparing this lens with Canon 18-200 and Tamron 18-270. Bought this for these reasons:
1. Cheaper than the other two.
2. Lowest barrel distortion
3. Better build quality compared to canon
4. Has HSM. No USM on canon
5. Hood included
6. Highest number of SLD glass elements
Had it for 2 months now and used it in variety of conditions. Very happy with the result. I can only compare it with canon 18-55 kit lens. Surprisingly, sharpness of this lens is better than the kit lens. It has faster and quieter focus too (due to HSM). The OS works flawlessly. At 250mm I can see the image stabilize in the viewfinder after abt 1/2 second. Build quality and grip feel is very good. Hood is pretty solid too. Hood and filters do not rotate while focusing. Due to its weight I still use 18-55 indoors.
