Notes on Sigma 28-70mm f/2.8-4 DG Aspherical Large Aperture ...- The lens was shipped in good order within the specefied time, however it wasn't shipped with a lens cap or case as the Sigma factory does. I am satisfied with the workings of the lens considering the low price. I like the fact that it is compact and light.

Notes on Sigma 28-70mm f/2.8-4 DG Aspherical Large Aperture ...- 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.

Notes on Sigma 28-70mm f/2.8-4 DG Aspherical Large Aperture ...- it's fine for lots of situations but after using it for a few days i found myself wanting something with image stabilization. any shots above 55mm in low light were hard to get without some blur from camera shake. also, the focus ring on this thing feels pretty loose. overall i'm pretty happy with this lens. it's small and good for those times when you don't want a bulky, overbearing camera. in retrospect i wish i could have spent $400-$1000 on a really good lens.

Notes on Sigma 28-70mm f/2.8-4 DG Aspherical Large Aperture ...- 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).

Notes on Sigma 28-70mm f/2.8-4 DG Aspherical Large Aperture ...- This is a cheap lens, but for the money, it doesn't get much better. Great walk-around lens. Excellent if you are looking for a lens to use in whatever everyday situation you encounter. It is fast, it is easy, it has great DOF, large aperture, solid build, fast focusing, sharp pictures, and low price. you can't ask for much more than that, especially if you are paying so little. Get it, and buy it from me because MY lens WORKS. 5 stars. worth every penny.
