    Hey,
    Does anyone have experience with both of these lenses?
    I have the 18-50 but I require a bit more reach which is the main reason why I would want the 17-70.
    I understand the obvious differences b/w the 2 lenses (18-50 is a 2.8 throughout the range while the 17-70 isn't, and the 17-70 is an extra 20mm)
    What I want to know is: is there any other significant quality difference between theses lenses, or a difference in performance, that would keep me from selling the 18-50 and buying the 17-70?

    Thanks in advance

    I have the 17-70 as my walk-around lens and love it. The only hassle is the filters can be pricey (72mm) My polarizer was over a hundred buckaroonies. It is a very versatile lens and not to pricey.

    I just bought the 17-70 and it will be my walk around lens for sure. I cannot beleive how sharp it is. Yes the filters are pricey, just paid $86 for a polarizer today. Here the 1st picture I took with it just last Friday. No editing (except for sizing) right out of the camrea. You won't be disappointed with this lens.[​IMG]
