Bought an Nikkor AF 70-300 zoom for my wife's D3100. It won't work since it needs an external AF motor. Is there any way to use it in my FM3A? It's a nice lens in a focal length I want, so... Thanks for any input & yes, I know it's a "gelded" lens - that's why I'm asking.
Sorry, but there is no 70-300mm Nikkor that can provide autofocus operation on the D3100 and allow aperture control on the FM3A. If you try using a "G" lens on the FM3A, the camera will meter as if the lens was wide open but always shot the lens down to minimum aperture when shooting.

Erm, yeah, I was writing that at work, you are correct of course. I looked them up the other day, and the 17-35, 28-70 and 80-200 are the only zooms, and besides the 300 f/4, the rest are super teles.
However, none of the AF-I lenses will autofocus on a D3100, it doesn't support them.

The AF-I lenses do have in-body focus motors, and will focus fine on the D5000, D5100 and D5200.
However, the D40, D40x, D60, D3000, D3100 and D3200 are listed as incompatible if you call Nikon, their statement is that the older AF-I lenses use different motors with different electrical requirements than AF-S lenses. Several low-end film bodies also work with AF-S but not AF-I.
So while it might work, it's at least unsupported.
