what is af-s dx nikkor lens null

af-s means it is for nikon camera that needs auto focus motor built into the lens to auto focus. Unlike other models that have autofocus motor built in the camera body. DX and FX are two different types of camera lenses. FX are on more pricy model. see nikon website for fulll description.

Nikon offers two types of autofocus digital camera bodies: those with a built-in focus drive motor and those which require a lens to have a motor. Camera’s such as the D3100 do not have a focus motor in it so they require the lens to have the focusing motor – an “AF-S” lens. While these bodies can use a lens with no focus motor (an “AF” lens) you would have to manually turn the focus ring to bring the subject in to sharp focus.
