much better (2008-11-18)
Great little lens. I am really happy with Sigma.. this is my second Sigma lens.. although it isn't quite a canon it does a great job.
You get what you pay for. (2008-11-14)
I received this lens as part of a package on eBay, along with a Canon XTi. On paper it looked to be better than the Canon kit lens.
The image quality is nice although not outstanding. The real gripe I have is that the auto focus is nearly useless. Most of the time, the focus is off just enough that the photo is too soft to be usable. (By "soft", I mean "out of focus". I know the difference between soft and short DOF.)
Occasionally (maybe 10% of the time) the AF will go into what I call "thrashing." It will get near the correct focus and then it will jitter back and forth focusing just a bit close then too far, never settling on anything. I'm looking to unload it on eBay, but I doubt I will get enough money to make it worth the effort.
Love it! (2008-06-16)
This is the first of 2 Sigma lenses that I have bought. They're extremely sturdy and well built. I probably won't buy any other brand now considering the value of the product.
Great in Low Light! Cheap and produces soft image (2008-05-18)
First of all you can't expect this lens to be great. It is cheap and it's build cheap. However the best way to use this lens is in manual mode because you will have to set it at a high aperture F8-F22 outdoors. Indoors you have to use the flash for the high aperture settings. If you use this lens in automatic mode in the camera, you will get a very soft image, you have to learn the manual mode to get a decent picture with this lens. View the image samples from this lens
Great value for the money (2008-01-18)
Sigma 28-70mm f/2.8-4 DG Aspherical Large Aperture Zoom Lens for Nikon SLR Cameras
I was looking for a zoom lens for indoor sports shots. I didn't want to pay the big bucks of $750 to $1500. The Sigma fit the bill. At 2.8 it gives enough light for a decent shutter speed. The quality appears good as well. Although I have not blown pictures to 20x24, I can not tell the difference compared to expensive lens I have rented costing ten or fifteen times more. It also works well for indoor and flash photos. For my money, it does what I need.
