Hi, there are 2 versions of this lens. One is an SMC version, and the other is not SMC. This is marked on the lens, and the rubber grips on the focus/zoom ring are different - the non-SMC version has longer gnurls (or are they knurls?).
The non-SMC version has an enormous amount of slip in it - it's absurdly loose, but that can be surprisingly useless, and it's actually a good lens all round. The SMC version has some slip, but not a huge amount.
