Overview

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.

Pros & Cons

👍 Pros

  • The 0.95-1.35:1 throw ratio puts the ET-EMW500 firmly in short-throw territory, letting installers fill a screen from a comparatively close mount
  • Bright f/1.8-2.35 aperture range helps preserve light output from the host projector across the zoom range
  • Designed specifically for the PT-MZ16K, PT-MZ13K, and PT-MZ10K, so compatibility within that projector family is unambiguous
  • Supports both 16:10 and 16:9 aspect ratios, matching the two dominant formats for corporate, education, and venue screens
  • Zoom range gives installers flexibility to fine-tune image size on-site rather than committing to a single fixed focal length

👎 Cons

  • Locked to Panasonic's PT-MZ16K, MZ13K, and MZ10K bodies, so owners of other projector families cannot use this lens at all
  • Short-throw optics with this aperture range are typically premium-priced compared with standard-throw alternatives in the same lens lineup
  • A 0.95-1.35:1 range is short-throw but not ultra-short-throw, which may disappoint venues looking for sub-1:1 extreme wide coverage
  • Source text does not list optical resolution support, lens shift range, or motorized control specifics, leaving integration details to verify
  • Aperture narrows from f/1.8 at the wide end to f/2.35 at the long end, meaning maximum brightness varies with zoom position

Frequently Asked Questions

The PT-MZ16K, PT-MZ13K, and PT-MZ10K. It is designed specifically for this Panasonic projector family and is not a universal lens.
0.95-1.35:1. That places the ET-EMW500 in short-throw territory, supporting closer projector-to-screen distances than a standard lens would allow.
16:10 and 16:9. Both are covered by the lens design, matching the common screen formats used in corporate, education, and venue installs.
f/1.8 to f/2.35 across the zoom range. The widest aperture is available at the short end and narrows as the lens zooms in.
No. The ET-EMW500 is built for the specified Panasonic PT-MZ series bodies and is not intended for use on third-party projectors.
No. Ultra-short-throw lenses generally fall below a 1:1 ratio for most of their range; this lens is short-throw at 0.95-1.35:1 rather than ultra-short-throw.
