Tamron 90mm macro, non-Di
Discussion
I have an opportunity to buy a Tamron 90mm AF SP Macro lens but I'm struggling to find out anything terribly specific about it's capabilities. It's not Di marked so I guess it's pretty old. The seller uses it on a Nikon D7000 which has it's own AF motor and has a cropped sensor.
I currently have a Nikon D5100 with no AF motor, I gather the lens is quite an old model so I'm aware it won't autofocus on my current camera body. This isn't necessarily a show-stopper as I plan to upgrade to a full-frame camera later this year.
Can anyone tell me if this lens will autofocus on a camera without an internal AF motor, and will it work correctly with a full-frame camera?

If it's an old lens it's probably screw-drive AF (ie needs motor in camera body), and will probably cover full-frame view (as all lenses did before crop sensors came along).
