I purchased a new Nikon D7000 and have 5 lenses in all now...
1. 35 mm 1.8G
2. 50 mm 1.8D
3. 18-55 mm 3.5-5.6G
4. 55-200 mm 4-5.6G
5. 18-135 mm 3.5-5.6G
I was leaning towards keeping 1-4 above and selling the 18-135 with my D40x body.
What would you do if you had the above lenses?
I tend to agree here, but find that I only need one "walk around" lens and the 18-105 works quite well for that here (would dump 3, 4 and 5 for the 18-105). The 18-135 is a great lens, but lacks VR. I might go for the 18-200, but it's pricey.
I have the 50mm 1.8D but find that I don't use it much and the 35mm G probably wouldn't get used much either. Not a bad choice, if you use them.
A lot of this really boils down to what you'll really use, and nobody can give exact advice on that.
What I love (outside of the "going to the zoo with the family" stuff): The 70-300 VR gets some good use here -- love that lens. Recently bought a 105mm VR Micro-Nikkor because I want to get more into macro stuff. This lens is "sweet" in every way, but I wouldn't take it to the zoo or the beach.
In reality, these "best lens" threads seem to miss the point because application is everything and nobody knows what you do better than YOU. It's funny that we're willing to make recommendations without knowing the application. The 50mm D is a great portrait lens (but, I don't do much of that, so it rarely gets used here). The 70-200 2.8 VR is a killer birding lens; but I don't do that, either and can't afford one. (The work I see is stunning; just not my "bag.")
Point is, we buy SLR's largely for the lens interchangeability, but when it comes down to lenses, we lose reason. Think about what you'll use it FOR and this will become a lot more obvious.
In the bag for an upcoming beach trip to Mexico next year: D7000, 18-105 VR, 70-300 VR, a Canon SX30 superzoom P&S and a pretty well used Canon 780SD pocket cam. That's what fits this application for me; each has it's purpose. These would all be bad choices if portraits were the goal.
Think first, buy later. It'll save you some coin.
