Im just interested in knowing if your camera has a focus motor & so does the lens, which one takes priority over the other. Can you turn either off or on to use the best (quietest) one of your choice?
And is there any reason to buy a new lens with a motor in it for the D7000 which already has a focus motor?
Thanks in advance for any feedback !

Where did you get the idea that your camera body has a focusing motor?

A lens with a built in motor does not have a drive attachment to connect with the camera motor. You have no choice to make. Furthermore, if the camera has no internal focus motor & the lens has no internal focus motor you have to focus the lens manually. The newer lens ( AF-S) are typically faster to accuire focus than the older(AF) lens that rely on the motor in the camera.

I stand corrected. I wasn't aware the D7000 had a focus motor. Apparently it does.

Q. What are Nikon cameras that have a focus motor within the body and NOT the lens?

A. D90 and above models

D90, D7000, D300, D700, D800
They are a good buy, as you can cut expenses buy getting AF lenses which are cheaper than AF-S lenses.
But [in] AF-S lenses the autofocus is much faster and smoother. Also its better to have body motor as you have the option of using both AF-S lenses if budget permits or AF lenses if budget is tight.

I think I need to re-phrase my question, I know the cameras that have focus motors, I have the D7000 & my D50 actually has one too.
What I'm asking is what motor is working when you have a camera & a lens connected that both have motors ?

Thanks

As has been answered before, if both your camera body and lens have an AF motor, the lens one is used. And that's the way you'd normally want it.

I think BOTH of your questions were answered in the 2nd post following your original post. If my explaination wasn't clear, let me know & I will try to re-word it for you.

Perhaps from the older autofocus dlsrs which have the focus motor built into the body? Nikon D50, D70, D80, D90 and other newer models models that I am not too familiar have focus motors in the body. Each of those will also focus the newer AF-S lenses with the focus motor built into the lens.

Don't know much about Canons, but I would suppose the situation is the same with them.

The camera will give priority to the AF-S lens (the one with the motor in the lens) when it is attached to the camera. No urgent reason to buy new lens. Some of the older lenses that require a motor in the camera body were designed for the film version auto focus cameras, but they work fine on digitals.
