Panasonic ET-D3 35-50.9mm Zoom Projector Lens

Overview

The Panasonic ET-D3LES20 is a motorized zoom lens designed for professional use with Panasonic 3-chip DLP projectors. It offers a focal length range of 35 to 50.9 mm, enabling flexible adjustment of image size without moving the projector. This lens maintains a bright f/2.5 aperture throughout its 1.5× optical zoom, ensuring consistent brightness and sharpness across different screen sizes and distances.

Equipped with a built-in stepping motor, the lens allows smooth and precise zoom and focus control from the projector’s control panel or remote. Its integrated EEPROM stores calibration and operational data, preserving settings even after transport or lamp changes. This makes it a reliable choice for venues where projector placement and screen size vary frequently.

Key features

• Motorized 1.5× optical zoom enables quick and accurate throw-distance adjustments without physical repositioning of the projector
• Consistent f/2.5 aperture throughout the zoom range maintains image brightness and quality regardless of zoom level
• Stepping motor provides fine control over focus and zoom, ideal for installations where the projector is mounted out of reach
• EEPROM memory retains lens calibration and operational data to ensure consistent performance after transport or maintenance
• Throw ratio adapts to different projector models, covering 1.67 to 2.41:1 on PT-RZ31K and PT-RS30K, and 1.79 to 2.59:1 on PT-RQ32K
• Direct compatibility with Panasonic PT-RQ32K, PT-RZ31K, PT-RS30K, and other 3-chip DLP projectors simplifies installation without extra hardware
• Designed to deliver sharp, evenly lit images across large venues such as auditoriums, houses of worship, trade shows, and outdoor mapping events
