Sigma 18-50 f2.8-4.5
I was just wondering whether the Sigma 18-50mm is overall a good lens. There are very few online sources that have actually reviewed it and have information about it. I know that getting internal focusing and zooming, OS and HSM all for only $200 seems very good. However I do not know anything about how sharp the lens is and the overall image quality as well as the focusing speed. This is for my Canon 60d by the way.
Thanks in advance,
