Good value for the cost

Excerpt: I use the lens as my 'normal' lens; it's the one always on my Canon7D. Focus is sharp and the IS function works well. It's lighter than my old 10-200 with a filer size of 62mm vs 72mm. So far, I'm pleased with it (only used it for a month).
Excerpt: Very practical for travel, children and, in my case (I have two wide angles), using it as telephoto. The lens is very well built, but the focus ring is a little loose. Sharpness is pretty good if you stop down, but wide open could be better. See below two images (@100%): i) center (@200mm) and ii) extreme corner (@200mm).
Excerpt: I received the newly released "Sigma 18-200mm F3.5-6.3 DC OS HSM" lens a couple of days ago and my initial tests have been quite impressive! I have only had a chance to do a quick direct comparison of the Sigma 18-200mm lens to the "Canon ef-s 55-250mm f/4-5.6 is ii" lens that came with my Canon SL1 DSLR. So far, the Sigma zoom lens appears to be noticeably sharper than the Canon zoom lens.
Excerpt: I had higher hopes for this lens. The Sigma 17-70 is in my bag and is leaps and bounds better than this lens. The clarity just isn't there and I have to push my ISO in order to get the image. If it's not too late, I'm returning this lens and will do more research and save my dollars to afford a quality lens.
Excerpt: This is my first non-canon lens. I am using it with T3i The Good - Solid build. Compact and Lightweight. Fast, accurate, and reasonably quite Auto Focus. Good IQ for the price. Zoom Range (29 - 320 for T3i) Outdoor closeups are great, it gives smooth background blur @200mm. The Bad - It creeps. It can be locked only at 18mm. Some stickiness in zoom mechanism at mid-range.

Summary: This is a nice lens . It's very sharp from 18mm-75mm with very low distortion. From 75 it is a bit soft at the corners but still sharp in center . at about 100mm it's soft again getting sharp by 135mm and at 200mm it's quite good for an inexpensive lens. It's built is remarkable for a lens at this price. OS system is very effective giving me about 2 or 3 stops .Colors are a bit warmish but that is very subjective in nature.
Pros: Built , overall good sharpness , effective OS
Cons: Inconsistence in sharpness , prone to veiling flare , heavy

Summary: I have never had a Sigma lens before for any of my previous DSLR's but decided to purchase this Sigma 18-200 for it's large zoom (11.1X) and also its large filter size(72mm) Having optical stabilization was another factor in my buying this lens. I have been very satisfied in the pictures I took with this lens which have been mostly landscape that have shown very sharp detail.
