Panasonic ET-D3 35-50.9mm Zoom Projector Lens

The Panasonic ET-D3LES20 is a motorized zoom lens created for professionals who use Panasonic 3-chip DLP projectors and need a flexible way to fine-tune image size without moving the projector. With a focal length that ranges from 35 to 50.9 mm, it lets you adapt to different screen widths and distances while keeping setup time under control.

The lens delivers a 1.5× optical zoom and maintains a bright f/2.5 aperture across the full range. A built-in stepping motor allows smooth, precise adjustments from the control panel or remote, so focusing and zooming stay accurate even when the projector is mounted high or tucked into a tight rig.

An integrated EEPROM stores calibration and operational data, which helps retain lens settings after transport or lamp changes. On the PT-RZ31K and PT-RS30K the throw ratio covers 1.67 to 2.41:1, while on the PT-RQ32K it spans 1.79 to 2.59:1. This range suits large venues such as auditoriums, houses of worship, trade-show halls, and outdoor mapping events where screen size and projector position often change from one job to the next.

Rental houses, staging companies, and fixed-installation teams will appreciate that the lens attaches directly to compatible models like the PT-RQ32K, PT-RZ31K, and PT-RS30K without extra hardware. The result is a dependable tool for delivering sharp, evenly lit images across wide stages and expansive screens.
