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.
