Hi people,

I have searched through the archives here, and did not find enough info on what it is I am looking for. So here it is: I am trying to decide what zoom lens to purchase next. I sold my kit lens (17-55 VR), cause I really did not like it a lot. Now I am missing the range. So here I am, looking at the
  1. Sigma 17-50mm F2.8 EX DC OS HSM
  2. Sigma 17-70mm F2.8-4 DC Macro OS HSM
  3. Sigma 18-50mm F2.8 EX DC Macro HSM
  4. Sigma 24-70mm F2.8 IF EX DG HSM
  5. Nikon AF-S DX 16-85mm f/3.5-5.6ED VR II
  6. Nikon AF-S DX 17-55mm f/2.8G IF ED
  7. Nikon AF-S 24-70mm f/2.8G IF-ED


Now from a price point of view the Nikons are just horrendously expensive when you get into the f2.8 range. So my questions are these:
  • Is the extra price you pay for the Nikon really going to make a difference on a D5000?
  • Does anyone have any experience with any of the Sigma lenses?
  • I read in one thread that the writer was very happy with the Nikon 16-85. Anyone out there to veryfy this?
  • Given the fact I have the smaller sensor, does it make sense to get a 24-70 in the first place? (I have no intention to go full frame)


Any help would be appreciated.
