Conclusion: Excellent Lens - slightly warm tones - fixable though
Review: This is a very nice lens - I read several reviews and decided to go for it. The colors are a bit on the warmer side (more red than reality) - but you can fix it either on the camera (by lowering saturation) or on ACDSee (reduce red color).
Perhaps a bit on the soft side, but I am learning that DSLR images are great and lend themselves to sharpening with any software without much noise or artifacts. After a tad bit of sharpening, its difficult to tell the picture apart from a much more expensive lens. Very nice background blur, so portraits at the park, or garden, or the beach look fantastic.
Very pleased with the lens - for $149 its an amazing product.
Evaluation: 
Conclusion: overall- satisfied. especially for the price
Review: Given the specs on this lense, you should only expect to be able to use it at the long end of the telephoto range in good light levels.
Overall - i've been absolutely satisfied for it, and can't get over the price. The only time i found myself wanting for a better lense, was an indoor graduation, low light levels, from very far away. The shots were dark, and when i slowed it down a bit to let in more light, i obviously got blurry pics.
In every other situation, and in the mid telephoto ranges - the image quality has been excellent, and have not had a problem with the light.

Conclusion: Great Beginner Lens
Review: New to photography, I decided to read a multitude of reviews on the camera itself as well as the kit lens. Like many who read the reviews, I found that near 90% of the reviews were not in the kit len's favor, and thus decided to search for a different lens to go with my canon Xti body. I debated between this lens and the 70-300, knowing that the 70-300 would be better for sports, but much less useful for those group/portrait shots. I then found this nify little lens and decided, knowing that the Xti has a 1.6x multiplier, that the equiv. of a 88-320 would be just fine compared to the 70-300. Budget was also a concern and I was able to eventually find the Sigma for under $150. This lens isn't the quietest, fasest, or sharpest lens available, but it sure does the job for shooting well lit sporting events and more than does the trick for a new photographer looking to really get started with a dSLR!
Evaluation:
Conclusion: A little loud, but sturdy and good range
Review: This lens picks up where my standard 18-55mm left off. I have a Canon Digital Rebel XT. The motor of the Sigma is kind of raspy, but my ear is also closer to the motor than everybody else's. Another thing - I wish the zoom wasn't so stiff. Other than that, the lens is good value. I think an equivalent from the Canon manufacturer was in the $200 range.
Evaluation:
Conclusion: Great little lens
Review: I bought this lens hoping it would give me the over all photo lens capability for general photography I want. This lens for the money has come close to that expectation. It is a very good lens. I have shot close to 100 photographs of people and scenes, great clarity for the price. I have no complaints so far.
