That lens is motorized, for both focus and zoom, always a nice touch. (It's great to be able to stand a foot from the screen when focusing, so that you can be sure you have it as sharp as possible). It offers a 2:1 zoom ratio, which for a 100" diagonal, 16:9 screen, allows the front of the projector to be as close as 9 foot 10 inches or as far back as 19 feet, 8 inches.
Moving to the top of the PTAE2000U, you won't find the traditional control panel, but there are two rotary dial controls, one each, for horizontal and vertical lens shift. More on the lens shift in the General Performance section. Also, along the front edge of the top, are three indicator lights - the usual power/standby, temperature, and lamp indicators.
