DX is a lens designed exclusively for their APS-C sensored DSLRs, but can be used on their full frame cameras like 35 mm SLRs and full frame digital SLRs like the D3 series and D700 DSLRs. All lenses designated as DX type can be used with DX format digital SLR cameras. Many Nikkor lenses designed for FX or 35mm (135) film formats can also be used with DX format digital SLR cameras. The effect of using a Nikkor lens on a DX format camera will produce a magnification of the focal length of the lens by a factor of 1.5x (eg. a 50mm lens will produce the equivilant of a 75mm focal length).
G lenses do not have an aperture ring on the lens and must be controlled using the command dial on the camera.
AF-Silent Wave Motor (AF-S) is what Nikon calls their ultra fast Auto-Focusing lenses which utilise Nikons silent wave motor (~SWM). This system works by converting travelling waves into rotational energy to focus the optics the ultrasonic waves move in a spiral pattern inside the barrel with the motor positioned on top of the waves driving it from below.
