Auto Focus Motored Lenses w/ D90

[JewelsOK]

I am so sorry if this has been asked repeatedly, but my search did not turn up an answer. I have two lenses that I got to go with a Nikon D3000 that have the motor in the lens.

One is: Sigma AF 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) Zoom Lens for Nikon Digital SLR Cameras This one has a physical switch on the lens for AF or MF.

The other is: Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR Cameras. This one does NOT have any AF/MF switch on it.

My question is will these two lenses work with a Nikon D90 and if so, at what settings = what do I set the switch to on the lens if applicable and what to I set the switch to on the body of the D90.

Thank you so much.

Yup, just have both the lens and the camera on AF and you are good to go Obviously for the lens without AF, just make sure the camera body is on AF
