Panasonic ET-ELW20 1.3 - 1.7 :1 fixed zoom lens for PT-MZ880/MZ770/MZ670 Series, PT-EZ770 Series, PT-EZ580 Series and PT-EZ570 Series projectors

Product Overview

The Panasonic ET-ELW20 is a 1.3–1.7:1 interchangeable zoom lens for compatible Panasonic commercial projectors. It lets integrators vary projection distance by changing focal length, so a fixed-mounted projector can reach the target image size from a range of throw distances. As a factory Panasonic optical assembly, this projector zoom lens is matched to the lens mount and optical engine of its supported PT-MZ and PT-EZ series projectors. It is well suited to mid-room front-projection installations in commercial AV environments.

Product Description

The ET-ELW20 covers a near-standard throw range of 1.3–1.7:1 with an f/1.8–2.3 aperture and a 20.4–27.6mm focal length, packaged in a compact ø4.6 x 7.7-inch barrel weighing about 2.6 pounds. Because it is interchangeable, AV designers can re-lens a compatible projector to fit a new room geometry instead of buying a new projector. It sits in the middle of Panasonic's ELW/ELT lens lineup for these projector families; for longer throw distances, compare the Panasonic ET-ELT22 (2.7–4.5:1) and Panasonic ET-ELT23 (4.4–7.1:1), and for ultra-short throw, the Panasonic ET-ELW21 (0.8:1). Always confirm the exact projector model against Panasonic's lens compatibility chart before ordering.

Frequently Asked Questions

Which projectors does the ET-ELW20 fit? It is designed for supported Panasonic PT-MZ and PT-EZ series commercial projectors. Confirm your exact projector model against Panasonic's current lens compatibility chart before ordering.

What throw ratio does it provide? 1.3–1.7:1, a near-standard range for mid-room projection geometries.

Is the lens interchangeable in the field? Yes. It mounts into the projector's lens bayonet, so a compatible projector can be re-lensed for a new room without replacing the projector.

How does it compare to other ELW/ELT lenses? The ET-ELW20 sits mid-range; the ET-ELT22 and ET-ELT23 reach longer throws and the ET-ELW21 covers ultra-short throw. Choose by projector-to-screen distance and target image size.
