Panasonic ET-D3QS400 1.4 – 2.1:1 Zoom lens for PT-RQ50 projector with Lens Memory and Stepping Motor

Product Overview

The Panasonic ET-D3QS400 is a powered zoom lens for the PT-RQ50K 3DLP laser projector, delivering a 1.43 to 2.09:1 throw ratio in 4K 17:9 mode. With a 1.4x zoom range and a 45.3 to 65.6mm focal length, this PT-RQ50K projector lens covers standard mid-throw placements in auditoriums and large staging environments. A stepping motor and auto lens identification support repeatable, motorized setup in permanent commercial AV installations.

Product Description

This interchangeable lens is purpose-built for the PT-RQ50K, Panasonic's native 4K 3DLP large-venue projector. The 1.43 to 2.09:1 throw range suits rooms where the projector sits at a standard distance from the screen, and motorized zoom and focus with lens memory allow operators to recall framing presets between events. Auto lens identification lets the projector recognize the fitted optic and apply the correct geometry, which reduces setup time in rental, staging, and fixed-install workflows. The f/2.5 aperture maintains brightness across the zoom range to take full advantage of the projector's high light output.

This lens fits only the Panasonic PT-RQ50K projector. For a wider placement, see the ET-D3QW300 (1.1–1.7:1); for longer throws, compare the ET-D3QT500 (2.0–3.4:1) and the ET-D3QT600 (2.7–3.9:1).
