9 out of 10 points and recommended
I got this lens (Nikon mount) in HK last week and took a number of shots on Sunday.reviewed March 10th, 2009 (purchased for $820)
Pros : No front-focus issue was found. AF is very fast and resolution throughout the range is high. The IQ is aharp and better than my Nikon16-85mm and Sigma 18-50mm EX f/2.8 lens. Colour rendition is excellent.
Cons. : The filter is expensive for 82mm which costs me US$118 for B+W. The wide angle is not enough for indoor shot with my Nikon D90. It also feels a bit heavy compared with 16-85mm. VR is not included.
Conclusion : This is a very sharp and high-resolution lens. It will be prefert with VR function.
