Is the Tamron AF08N700 auto focus with the D90?

Hello Amian,
Here is a link to the manual of your camera that may be helpful to you.
Good luck,

Did you switch the AF / MF switch to AF (Auto Focus)?
It is on the lens.

Tamron makes their lenses with a variety of lens mounts. If your lens has a Nikon mount then it will mount onto the D90.

This lens is compatible with your Nikon D90 according to this site:

Your complaint "does not work" is rather broad, so I don't know what specific kind of problem(s) your having with it.

If you continue to have issues with it, make sure other lenses work on your D90 to eliminate the body as the source of the problem. Consider performing a 2 button reset on the D90 (and resetting any other customized settings to defaults) and try again. If it still "doesn't work" then contact Tamron to evaluate the lens for possible repair.

Good luck!

Try cleaning the lens and camera contacts gently with a lint-free cloth

The Nikon D3000 does not have a focusing motor built-in, relying on the lens to have a motor. The Tamron AF 55-200mm does not have the necessary motor; it only auto-focuses with Nikon cameras that have the motor in the camera body.

For Nikon lenses, you need lenses designated AF-S. For Tamron, you need lenses designated USD and/or BIM.

That probably wasn't the answer you wanted to see, but there it is.

Try a reset (hold down both buttons with green dots next to them) and see if that helps.

Also try cleaning the contacts on the lens itself (light rub with a pencil eraser usually works well).

This is a lens for Sony/Minolta cameras. It is not compatible with the Nikon D90. Hence a Teleconverter for Nikon will not work on this lens to mount it to a Nikon D90.

My first suggestion is to send it back if it is under warranty.

The grease probably got so thick, from the cold, that it caused too much resistance for the auto-focusing mechanism. You probably have damaged the focusing mechanism in the lens. You cannot repair this, yourself. I don't know how cold is too cold but it really shouldn't have done that.... Tamron makes cheap lenses. Try and exchange it for at least a Sigma.

if it is an auto focus lens that works on one eos camera, it should work on almost all of them. the only known exception is that some high end extenders will not fit the eos1dmarkII as it protrudes into the opening too far.
but a good rule is that if it fits without any obstruction issues, it should work. try cleaning contacts on the lens and camera body. if that doesn't fix it, talk to Tamron. you can use it manually, but will not be as easy and you would get less predictable results.

my suggestion is to always go with lens from camera maker.

sounds like there is an issue with the tamron lens. not the camera.
good luck
