Panasonic ET-D3QT700 3.9 – 5.5:1 Zoom lens for PT-RQ50 projector with Lens Memory and Stepping Motor

Product Overview

The Panasonic ET-D3QT700 is a telephoto zoom projector lens built exclusively for the PT-RQ50K 3-chip DLP laser projector, delivering a 3.89 to 5.47:1 throw ratio in 4K 17:9 projection. With a 1.4x zoom range and a 122.8 to 172.3 mm focal length, it is a long-throw lens for large-venue installations where the projector must sit well back from the screen. Auto lens identification, a stepping motor and lens memory make it a practical choice for rental/staging and fixed commercial AV deployments.

Product Description

This PT-RQ50K zoom lens covers long projection distances in auditoriums, large houses of worship and broadcast environments where the projector is rack-distant from the screen. The built-in stepping motor supports motorized zoom and focus, while lens memory stores positions for multi-format events that switch between aspect ratios. Auto lens identification lets the projector recognize the installed optic and apply the correct geometry. The ET-D3QT700 is one optic in a dedicated PT-RQ50K lens family; for shorter distances on the same projector, the store also carries the ET-D3QT600 and ET-D3QS400, and for the longest reach the ET-D3QT800. The host projector is the PT-RQ50KU.
