Utilizing EXIF data, is there any way to have an keyword created and/or assigned to an image based on the metadata of that image?

Specifically what I'm looking for is when an image is uploaded, in the exif is the model of camera used and the lens, I would like keywords assigned to that image based on those specific data items.

@plg, I noticed in the thread below, you said you imported a number of photos with the camera/lens information as tags, how did you do that?
