AF-S 300mm F4 D only likes old bodies?

I recently pickup up a used 300mm AF-D D for a very good price. It'll auto-focus just fine on my old N80 & D300 bodies, but it won't do anything on a D90, D5500, D7100 or D750. Is this the expected results? Anything I can do to solve the problem? All the digital bodies have the latest firmware.

Make sure the aperture setting is dialed over to the min, (highest number) on the lens and the autofocus still may not work with the 5500 as I believe its a screwdrive AF system. Only bodies that have the AF motor will drive the lens. Hope this helps.

It is. No, this is not a screw drive lens. Further searching on the 'net reveals that this is a common problem with early samples of this lens, which this one is. I'm still researching solutions... On the bright side, in it's current state it won't auto-focus any worse with my TC-14B than it does without it ;)

I tried one out. It's an AF-D lens so won't AF on your D5500 but should work fine on your other bodies. I have no idea why it wouldn't work other than what TT mentioned. Be sure the aperture is set to the smallest then use your aperture wheel to set whatever aperture you want to use.

The AF-D is an older, screw focused lens. I'm talking about the AF-S D lens, which has it's own focusing motor, and yes, when it's working properly, it'll work just fine on a 5500.

Oh THAT one. Now I understand. I have one here that I haven't used in a while since upgrading to the PF. Have you checked the mount to see if all the screws are tightened? I know mine worked fine with a D750 and D7100, but I don't have the latest firmware on those bodies. So sorry I can't help you with that.
