How do you you zoom the camera on the Pantech Hotshot?

If you phone is at maximum resolution (2048x1620, or something like that) it actually cannot zoom at all. If you change the settings (the little gear in the lower right corner when the camera is active) so that the camera resolution is something closer to 1620x1080 (again, from memory), when in the camera mode, if you tap the bottom of the screen, a slider bar will appear that lets you digitally zoom the view before you take the picture. Left is less zoom, right to increase zoom.
