Your Nikon D3000 does not have a Built-In Motor to drive "D" type lenses -- You need to buy AF-S lenses (Built-In Motor in the Lens) for this Nikon Body. You can buy Off-Brand Lenses that have the HSM motor built into the lens (Sigma).
if the lens does not have a HSM (built in motor) it will not auto focus. If it has a HSM, buillt in motor, ;ook on the left side of the lens for a switch ( A-M ), switch it to A- for autom and M- for manual focus.
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 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.
Yes, the AF Zoom-Nikkor 24-85mm f/2.8-4D IF is compatible with the D7000. Wide to Telephoto 3.5x zoom lens ideal for landscape, full length portraits, travel and portrait photographs. Fast f/2.8 maximum aperture at 24m setting is ideal for available light shooting or slow/rear flash sync techniques. This lens is a manual focus lens therefore Manual focus is available for lenses that do not support autofocus on the D7000. To focus manually, adjust the lens focus ring until the image displayed on the clear matte field in the viewfinder is in focus. Photographs can be taken at any time, even when the image is not in focus.
On most lenses the maximum aperture will decrease when you zoom in, as the optics move to focus at the new zoom range. These zoom lenses are said to have a "variable" aperture. To achieve the widest possible aperture, you need to be at the widest possible zoom setting.
