Good to see more choices, but we also need some variations in pricing.
The lens seems to be a good one, but the review, comparisons, conclusions and the words used there are biased and unprofessional. It is a one man's opinion out there on the web...
In order to compete with equivalent Canon or Nikon lenses, Sigma needs to be significatly less expensive, even if provides similar picture quality.
