The lens is great - on the Nikon D7000 in superfast autofocus and light dimmed and super sharp. Exactly what I expected. TOP! However, the selling at AMAZON lens I had to send back as soon as possible. I had ordered it again and then get one with significant signs of wear (scratch, scratch, scratch) and cleaning marks on the lenses. Apparently stored at Amazon used goods under new. If I want to buy used, then I will do that with pleasure, but then for 1/3 less price in top condition (so the prices at this lens are). I then with another provider, the lens newly bought for almost the same price. Since Amazon for himself no rating provides (impudence !!!), only 1 star. Read it!
