Digital SKunk said:I say get the 17-55 while you can. Waiting for an update with glass is crazier than waiting for an update with Apple. At least Apple give them every 6-8 months. The 17-55 is still "NEW" in terms of glass.
I've been reading a lot this last days about the 17-55, and it do seems an excellent lens that would last me a loooong time. Tho I have also read some pretty good comments about the new 16-85.
It seems that it has a good bokeh also, and the VR would let me take photos in low light situations. The only con that I see with this lens is that it may not be a much better lens than my current 18-55 kit lens.
Has the OP thought about Tokina? If you are looking for what the 17-55 gives you, in a Sigma like price, with much better build quality all around, take a look at the Tokina 16-50 f/2.8 This would be my choice if it wasn't for the lens extention during zoom, and build quality compared to the Nikon. Personally, if you have the choice to go with the 17-55, get it. It's the best you can get and will last a lot longer than you think.
Does it has internal focus motor? I haven't been able to find if it has or not.
