7 out of 10 points and recommendedaffordable fast lens, decent focus, compact and lightweightat this price point not many, but compared to $$$$ lenses, it's a bit soft at the edges
I've used this lens for several years and have been happy with its performance. I bought it as an affordable 2.8, used it in many scenarios from portrait to action to news. It's a great all around medium telephoto at a good price. If you're serious about a good deal, this is it. However, if you're serious about the highest performing 2.8 lens, you'd be better off looking at the Canon version, or the new ultrasonic focusing Tamron.reviewed May 28th, 2012
If you're in the market for this lens, I'm selling mine on ebay right now to upgrade to the Canon version.
