Bests & Worsts Reviews from Amazon

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.
