Yeah, whatever you do just don't get one from 47th St Photo. I just returned one to them. I had it over the weekend and it was horrible. When I asked them for a replacement, they told me that was the only one they had. So I had to return for refund and getting hitted 15% restocking fee and loose $20 in shipping + had to pay to ship this back to them.
ouch.
Restocking fee? You pay it for them to put it back on a shelf!
It happened to me once. The company were going to charge me a restocking fee for a pair of shoes that were faulty - the fee was more than the cheapo shoes!
I still have the shoes. Never worn 



Ill see how the 17-70 is as a portrait lens n ill keep you in mind as i think im only gonna use the 100mm for portraits in future!
