Evaluation:
Conclusion: great lens!
Review: Just receive my 18-50 Lens on Sat and get to do some night landscape shoot with this lens ! the image is clear and sharp! focusing is fast with the F2.8 stop... great lens for the price!
UPdate... have been using this lens for the past couple of weeks! the image is crisp and sharp! the fix F2.8 comes in handy in dark areas ! Have done some HDR shots .. Using it on a canon 40D!

Conclusion: AF issues, Chromatic abberations too severe
Review: Perhaps I was unlucky and got one of the bad ones but I found this lens completely unreliable. My first issue is the auto-focus (on canon 40D). I had more missed shots with this lens than I've ever had with any other..pretty slow AF also. I found the chromatic abberations unacceptable on a great number of shots as well. On the other hand, I took some beautiful macro shots with this lens. Particularly using live view with manual focus...fantastic. It seems that Sigma lenses are hit and miss QC wise from what I'm reading. Too bad because it really feels like a well built, quality lens. I returned mine to amazon as defective.

Conclusion: Very Nice Lens
Review: I have had this lens for nearly two years, frequently recommending it online and too friends so I thought I would take a few minutes and write up a review here. This lens is sharp, well made and comes with a nice hood and lens pouch.
The wide angle of 18 even with the 1.6x crop factor is excellent. You can get nice and close and still get your subject in the frame. This make compositions with distracting backgrounds much easier to deal with.
It is fast f/2.8 is great when you need it and again another option when you want to deal with blurring out distracting backgrounds or like the shallow depth of field look you can get with an f/2.8
When I first got my camera (Rebel XT) and lens I thought there was something wrong with the focusing or the lens or both. Turns out it just took some learning and practice with both. My point is some of these folks in the reviews and elsewhere that talk about focusing issues, some (not all) will find that with a little bit of patience and practice their camera "focus" problems will be gone.
Evaluation:
Conclusion: Great Lens
Review: This lens does everything the manufacturer claims. It is sharp, auto focuses well and is easy to use.
