If you plan to shoot inside sports, without flash, you are dead in the water without a 2.8 lens. You will need to spend some money.....

The 55-200 VR is an excellent for the money. Along with the 18-55mm will not break the bank and both will produce excellent results. I bought both for my wife's D40. Cheaper third party lenses will not compete with Nikkors. If you can afford a D90, which I have, get the Nikkors. If you want one lens to do almost everything get the 18-200mm VR, which I also have, it is the lens on my D90 every day...

You might start shooting inside so you will have better info as to what digital cameras are capable of producing. You will notice this was shot inside by my wife yesterday with no flash. The lens was a Nikon 18-55mm. Attachments:.

I recommend the 70-200 for indoor action.

If the lighting is good the 80-400 will give a lot more range.

Every day every where lense for the D90 is the 18-200, but does not have the low light or range of the other two...

Keep the 18 to 105mm as it is only a $150 when bought with kit, then add on from there, otherwise buy the 18 to 200mm and get a 11mm to 15, 16,or 17,mm when you can...

Got my d90 a few weeks ago along with nikkor 18-200mm vr II.

So far satisfied. will add the nikkor 70-300mm eventually...
