Panasonic ET-EMW500 Projector Zoom Lens

The Panasonic ET-EMW500 is a short-throw zoom lens purpose-built for the company's PT-MZ16K, PT-MZ13K, and PT-MZ10K installation projectors. The defining number is the throw ratio: 0.95-1.35:1, which sits in short-throw territory and gives AV integrators room to mount the projector closer to the screen than a standard lens would allow. The lens supports both 16:10 and 16:9 imaging, the two formats that dominate corporate, education, and large-venue projection. It is the kind of accessory that is chosen on a spec sheet rather than in a showroom.

On the optical side, the f/1.8-2.35 aperture range is brighter at the wide end and steps back as the lens zooms in, which is typical for zoom optics of this type. Because the ET-EMW500 is matched to a specific projector family, installers do not have to cross-reference mount compatibility or worry about generic adapters — it is Panasonic's own optic for Panasonic's own chassis. Beyond throw ratio, aperture, and supported aspect ratios, the source material does not detail features such as lens shift range or motorized positioning, so specifiers planning a ceiling or rear-projection install should confirm those details against Panasonic's official lens documentation before committing.
