Panasonic ET-ELW21 Fixed Short-throw Lens

The ET-ELW21 is a fixed-focus short-throw lens for Panasonic's PT-MZ and PT-EZ series 3LCD projectors, with a 0.8:1 throw ratio across WUXGA, WXGA and XGA. Its short throw and rear-projection suitability make it a fit for cabinets and tight rooms where the projector sits just behind or below the screen.

There is no zoom, so image size is set by projector placement and lens shift. The lens uses a 108 mm barrel, weighs about 1.08 kg and drops into the projector's interchangeable mount. It fits the PT-MZ880, MZ770 and MZ670 series along with the PT-EZ770, EZ580 and EZ570 series.
