For what? A particular camera? As a telescope/viewing thing?
There are some cheap surplus lenses of various sorts available that might be useful, eg 12-72mm F.14, $20

side-to-side motion is usually called "panning", and you can get motorized pan units "off the shelf" that just about any camera will mount on (however, they tend to be expensive.) Zooming is a change in magnification (but the center of the picture stays in the same place.) Zooming might do what you want, but it's not clear...

There are a few complex issues to deal with - the actual movement (extension) of the lens(es), the focal length of said lens(es), etc.
