26 May 2011
Conclusion: Overall this lens performs extremely well and produces some excellent shots. In the specialist areas where it would be used, such as Wildlife and sports, it proves easy to handle and, just as importantly, carry.
Pros: Good build and finish, Fast quiet autofocus, Very usable wide open, Manageable for its type, Close focus distance is good.
Cons: Lacks a little contrast, Hood a little short for the focal length.
