For the cost minded person who is not a pro you can fool most people...

Summary: I rate this high because it's affordable and like most lenses under $500 there are often trade-offs. The price is often so remarkable for these that any negative issues are simply erased. I agree with the other reviewers before me so I'll skip repeating what's been said. When it comes to trade-offs you are sacrificing one thing or another and mostly quality (IQ).
Summary: This review is based on sample of one in late 2010. I have been an avid photographer on film and digital, but not a pixel peeper; for the amount paid, this lens is more than I expected. Good: super-wide FX on Nikon D700. Great details on center and some corners. Color rendition is fine. Bad: Not able to get sharp results on one corner at infinity focus, doesn't matter what the setting is. Sigma quality control issues are well known, lens possibly de-centered.
Summary: I wanted a good wide-angle lens for my D200 DSLR. In film, my favorite lens was a 19-35, but that didn't cut the mustard for my wide-angle needs. And a 12-24mm lens was a bit out of my price range. So, I took a leap of faith with this in-between, and I'm quite glad I did. The focal range is quite good, and it's extremely sharp, too. It doesn't have a built-in motor, but focusing is still fast and sharp.
Summary: I purchased the Sigma 15-30 zoom specifically for use on a digital SLR, so most of my photos will be taken in the sweet-spot in the center of the image. I prefer zooms on digital SLRs because changing lenses creates a dust problem with them, so the less you have to change them the less often you have to clean. The sensors are remarkably easy to damage, so any cleaning is a risk.
