5.0 out of 5 stars All around winner for an all around lens., May 27, 2009
Amazon Verified Purchase( What's this?)
This review is from: Sigma 18-250mm f/3.5-6.3 DC OS HSM IF Lens for Canon AF Digital SLR Cameras filter size 72 (Electronics)
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... Read more

4.0 out of 5 stars Sigma 18-250 Canon Mount - good quality/price, May 27, 2009
This review is from: Sigma 18-250mm f/3.5-6.3 DC OS HSM IF Lens for Canon AF Digital SLR Cameras filter size 72 (Electronics)
I was hesitant when it came to this lens. I have had Sigma lenses for >10 yrs and liked them, but found little to know information about this lens and was leaning toward the Tamron 18-275. The Sigma was about $30 less and I have never had trouble with my 3 other lenses. I even had Sigma replace one whose chip did not play well with my 20D, so I feel some loyalty to them. On preliminary use, it is about a pound and feels solid, and well made. Some complained about the mechanism being tight about half way from 18-250, I did not find it any more tight then my 28-70 or my 70-300 both by Sigma. The images are sharp generally except for the extremes on either end, so I will just avoid the very end of each side of the zoom range. I have not put the stabilization to the test yet, from what I can tell it does add about 2 stops and makes the hand held shots passable at longer focal lengths that would not have worked with out it. The other bonus is the rapid focus and quiet operation of... Read more

5.0 out of 5 stars Great lens for the price, September 6, 2009

This review is from: Sigma 18-250mm f/3.5-6.3 DC OS HSM IF Lens for Canon AF Digital SLR Cameras filter size 72 (Electronics)
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.
