how much are you willing to spend? because the way i look at it is: buy the best you can afford and you will never be disappointed... if that is a pro level lens then so be it... no upgrading needed later on ;)

I'm going to be forking out £500 on a new lens (onestop digital is my saviour - the lens costs about £620 domestically) in about 2 weeks and that is basically because i know that it will be a great asset in my lens bag for years to come.

Man is the dream of the Dolphin"
