Jim,
I am searching the docs for a good answer but I think that the camera comes under the "do not modify" list. I have not found anything in the rulebook yet. At anyrate, the focal length of the supplied lens give enough of a field of view to track the intended target(s) and the GDC keeps this factor in mind when working on the game and field components.
For other applications, I have seen vendors who have other lenses for this camera. I you search for CMUcam, you will find a number of outlets that also sell accessories. One of them is bound to have a lens. The current lens gives about a 60 degree viewing angle in the horizontal and less in the vertical due to the 4:3 aspect ratio.
