Default Lenses with built in motor ID

Well I have seen one thread and I guess there may be more to come, where members are looking at replacing their D50/D70/D100 cameras with newer versions, thereby begging the question of lens compatability.

Most users probably have older lenses that require screwdrive to autofocus, and that does raise a compatability issue with the lower end modern cameras. As these are built down to a pricepoint the coreless in body motor to drive AF/AFD lenses has been omitted on a few models.

So time to refresh the compatability list. As of Jan 1st 2011 the following cameras will not autofocus screw drive lenses, and so WILL REQUIRE LENSES WITH a built in motor.
D40, D40X, D60, D3000, D3100, D5000

To help anybody identify if their existing lens has a built in motor or not, I have added a graphic comparing an AFS (built in motor) lens with an AFD (screwdrive) lens.
A second graphic shows the location of the screw drive on the camera body for those that can get a hands on test at a camera in a shop.
