10 out of 10 points and recommendedFast focus, sharp, cheap, sharp, looks quite cool , sharp and not as heavy as the real one.. and ehh.. did I mention sharp?So far none found
Oh yes: I finally got one! It's the ultimate solution for me since the Nikon 17-55 is out of my league -> at least according to my wife ;) BTW: I got the 'made in Japan'-version.reviewed June 5th, 2007 (purchased for $520)
Tack-sharp at f2.8/17 mm and very reasonable at f2.8/50 mm - from f4.0 and up it's unbeatable at 50 mm! Now that might be the ($100-) difference between this lens and the Nikon f2.8/17-55.
From this moment it's glued to my D200!! I recommend it to any photographer (both pro and amateur) with the need of a fast standard zoom.
