8 out of 10 points and recommendedgood picture quality, good sharpnesszoom ring a bit stiff, you can hear VC
I bought this lens a few days ago. It seems good built, pictures are good quality and sharpness. I don`t like zoom ring, it`s little stiff (at least for me). When you turn on VC, you can really hear it.reviewed April 4th, 2012 (purchased for $550)
I have made abot 200 fotos; AF is working good.
You can see some test shots I made on f2.8, 4.0 and 5.6 (17mm, 25mm, 35mm and 50mm). Pictures are re sized to 2400x1600.
