If you are referring to the D5000 and the new D5100 please take note that 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. Cameras such as these two 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.

This is a really good lens for indoor sport and portrait. Best value.

unless your camera has an internal focusing motor (and only higher end DSLRs do) you will need to manual focus using the focusing ring on the lens.

Awesome lens, by the way,
