First of all, you are looking at a low end lens. Don't expect to get the same results you would get from a $1000+ lens because it's not going to happen.I've had this lens for a couple of weeks and I'm pretty happy with the images I got from it. I bought this lens as a secondary lens. I use it mostly for family pics, or non-job related shootings.Personally, I think that for the price you can't beat it. It's a pretty decent lens. You may want to check some of the images that I uploaded here (product images).Bottom line. If you have big money to expend on an expensive lens, then go for it. But if you are looking for an affordable lens, this could be it.

Well, you get what you pay for. I was looking for an alternative lens that was in the Xt's kit lens range because I didn't have a lot of money. The Xt's kit lens stinks below f/8 & I didn't expect the Sigma to be "much" better but I bought it used on a deal. I put both on a tripod and shot the same building scene on a sunny day. I found the Sigma to have less purple fringing especially in the lower f-stops where the Canon was terrible. Both are good from f/8 above but I felt the Sigma was a little sharper & that's why I use it over the Xt kit lens. Autofocus noise doesn't bother me much and it focuses fast enough for me (non pro). Build quality feels better than the Xt kit lens. You get a plastic hood for it, not on kit lens. Just remember...it's a low end lens so the 2.8 is almost useless. Just about any point & shoot will look sharper at 2.8 than this thing. It's pretty bad wide open & there's no point in using it. But I knew that when I was buying it and use it for outdoors shooting & usually keep it at f/8 or above. It's very pleasing for the price when used this way. Just get a Canon 50/1.8 for wide open shooting for a low price.So I believe it is a little better than the Xt kit lens but don't expect any "real" performance from the wider apeture. 3 stars for good performance @ f/8 and beyond for low cost. (BTW, the Xt kit lens does go wider at 18mm which you might want to consider but I find it to stink also at 18mm even stopped down, so I didn't care about it being wider than the Sigma).

Decided to buy this lens after purchasing a [body only] Canon Rebel XTi. Comparing this with the Canon kit lens will reveal insignificant differences. Both decent lenses for basic still photos, but it really shoots as a 45mm-112mm lens because of the XTi's 1.6x field of view crop factor. Next step is an upgrade to a wider view Sigma 18-200mm lens [[ASIN: B000NOSCGM]]. I've seen photos with this lens that are stunning. Canon lenses are excellent, IMO, but they tend to be overpriced for the minimum quality trade-off with third party lenses like Sigma or Tamron.
