I'm getting a Nikon d7100?

What lenses do you recommend so I can use them for every picture?

I bought my D7100 without a lens and then bought a Sigma 17-50mm f/2.8 to use as my primary lens. I probably use that lens 90% of the time.

The 18-140mm AF-S VR is available bundled. It offers a very versatile range. It is reputed to have very good sharpness, but suffers from pincushion distortion through much of its range.

The 18-105mm AF-S VR is also available bundled. Very good sharpness, less distortion than the 18-140mm. Plastic flange.

18-200mm AF-S VR II has great versatility. Sharpness is probably best-in-class for 18-200mm lenses, but the price paid for this range could be noticeable when 24 MP is viewed at 100%.

The Sigma 17-50mm f2.8 HSM OS has a very good reputation for sharpness, that could make good use of the D7100's 24 MP.

What are you going to take photos of? You can do wonders with the 18-55. VR lens.
