I think your key consideration, 98k, is whether regard image stabilisation as a useful thing. If you do, then consider:
  • 17-55
  • 15-85
  • 24-105
  • Sigma 17-70


If you don't, then you probably need speed as a priority, and you would consider:
  • 17-55
  • 24-70
  • Sigma 17-70 (maybe)


Note that some lenses appear on both lists.
