G vs D Nikon lenses for Nikon D7000?

If i got the D lens, for less, does that mean I can't control aperture in the camera itself. What's the real difference here?

NO it means that the AF lens will not focus as fast as the AF-S lens, nothing else.

Your D7000 can use any AF, AF-I or AF-S lens. What the "G" means is that there's NO aperture adjustment ring on the lens

G lenses have no aperture ring on the lens themselves. This means that G lenses are not compatible with older film cameras because those older cameras lack the capability to control the aperture in camera. G lenses also happen to have a built-in motor that allows it to autofocus with entry level DSLRs such as the D3100 and D5100.

D lenses have an aperture ring around the lens which makes it compatible with both new and old slr cameras. They require a 'screw' style motor to autofocus, so it is not compatible with entry level DSLRs (it works perfectly fine on the D7000 though). The "D" actually means distance information, in which the lens transmit the distance info to the camera to more accurately determine exposure, but it's a feature that both "G" and "D" lenses share.

It's really up to you which one suits your needs better. There are some lenses that are available only in the "D" version. Furthermore, "D" lenses tend to be less expensive than equivalent "G" lenses because they are usually older. Optically though, both are very good though the G is probably a tiny bit better. So in the end, go for the G if you can afford it; if not, go for the D.

The "G" designation does NOT mean there's a focus motor in the lens, it only means there's no aperture ring. All "G" lenses include the "D" distance function.
