9 out of 10 points and recommendedExtremely sharp at F 2.8High Weight
I bought this lens a few months ago, and I'm still really happy with it. The strength of it is the extreme sharpness starting at F 2.8, right from the beginning. Also, the focal distance makes this lens great to experiment with. You can check out some pictures I used it for on my site:reviewed November 21st, 2012
If you travel a lot, the high weight might be an issue. So before buying, think about that problem.
