Panasonic ET-ELT23 4.4 - 7.1:1 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-ELT23 is a long-throw interchangeable zoom lens (4.4–7.1:1) for compatible Panasonic PT-EZ770Z, PT-MZ, and PT-MW series commercial projectors. It is the longest-reach lens in this family, designed for venues where the projector is mounted far from the screen — deep auditoriums, large worship spaces, and long projection rooms. As a factory Panasonic optical assembly, it is matched to the lens mount and engine of its supported projectors. Its 74.8–118.2mm focal length supports both 16:10 and 4:3 content depending on the host projector.

Product Description

With a long-throw 4.4–7.1:1 range (vendor spec table lists 4.6–7.2:1) and an f/1.8–2.3 aperture, the ET-ELT23 fills a defined screen from a distant mounting point and tunes image size by varying focal length. The compact 108 x 108 x 196mm barrel weighs about 2.65 pounds, keeping added mount load low. Because it is interchangeable, AV designers can re-lens a compatible projector for a new venue instead of replacing the projector. For shorter throw distances on the same projector families, compare the long-mid Panasonic ET-ELT22 (2.7–4.5:1) and the near-standard Panasonic ET-ELW20 (1.3–1.7:1), or the ultra-short Panasonic ET-ELW21 (0.8:1).

Frequently Asked Questions

Which projectors does the ET-ELT23 fit? It supports Panasonic PT-EZ770Z, PT-EW730Z, PT-EX800Z, PT-MZ670/MZ570/MZ770, and PT-MW630/MW530/MW730 series projectors, including L variants. Confirm your exact model against Panasonic's lens compatibility chart.

What throw ratio does it provide? The product title lists 4.4–7.1:1 and the vendor spec table lists 4.6–7.2:1 — the longest-throw option in this lens family.

When should I choose the ET-ELT23 over the ET-ELT22? Choose the ET-ELT23 when the projector must be mounted farther from the screen than the ET-ELT22's 2.7–4.5:1 range allows. Base the decision on projector-to-screen distance and target image size.

Is the lens interchangeable in the field? Yes. It installs into the projector's lens bayonet, allowing a compatible projector to be re-lensed for a new room geometry.
