I have a D-80. The only lense I have for it now is a Tamron 28-300. I am trying to decide which lense to buy next. I am looking for a lens for indoor use and outdoor landscapes. My current choices would be Sigma 10-20, Tokina 12-24, Sigma or Tamron 17 or 18-50 2.8 with or without macro. We will be vacationing along the northern CA coast this year. Planning to do the coastal drive, redwoods, wine country (probably hot air baloon ride there). With that in mind what lense would you recomend and why. TIA for any input.
