Summary: Having worked at Canon's technical camera USA hotline before, I knew that Sigma can make a decent lens for the price. I am 'stuck' using Pentax (*ist D) equipment due to $20,000 worth of 645 lenses I own so I didn't switch to Canon equipment when going digital.
Pros: Looks and feels good. Easy to zoom/focus. Nice finish and doesn't feel "plastic".
Cons: Image quality. Hopefully just a fluke. Will give them one more try.
