Panasonic ET-ELU20 Ultra Short Throw Varifocal Lens (5.43-5.82mm, f/2)
Experience immersive projection with the Panasonic ET-ELU20 Ultra Short Throw Varifocal Lens, engineered to unlock dramatic screen sizes from compact spaces. This innovative zero-offset zoom lens is designed specifically for DLP projectors, delivering exceptional image quality while simplifying installation in classrooms, conference rooms, museums, and home theatre environments. The ET-ELU20 combines precise optical performance with a flexible throw range, enabling you to place the projector closer to the screen without sacrificing brightness or sharpness. Its varifocal capability lets you dial in the perfect image size and focus across a wide range of throw distances, ensuring edge-to-edge clarity and uniform brightness that punch through ambient lighting. With robust construction and meticulous engineering, this lens helps you maximize your projector’s potential, delivering engaging visuals, reliable performance, and long-term stability in demanding usage scenarios.
- Ultra-short-throw versatility: The ET-ELU20 features a specialized ultra-short-throw optical design paired with a bright f/2 aperture, enabling large images to appear from very short distances. This makes it ideal for tight spaces like small classrooms, executive meeting rooms, and compact home theater setups where wall or ceiling space is at a premium. The lens minimizes throw distance without compromising brightness or color accuracy, so audiences enjoy a expansive viewing experience even in crowded environments.
- Varifocal precision for perfect framing: This lens provides varifocal adjustment, allowing installers to fine-tune the throw distance and image size with precision. Whether you’re projecting onto a standard screen or a custom wall, you can dial in the exact image width, achieve optimal focus across the frame, and reduce post-installation keystone corrections. The result is a consistently sharp, uniform image from edge to edge, with predictable scaling as you reposition or resize the projection.
- Zero-offset zoom for easier alignment: Panasonic’s zero-offset zoom design keeps the image anchor aligned with the projector’s central axis, simplifying installation and reducing the need for complex offset compensation. This translates into cleaner screen fills, less distortion near the image borders, and faster, more reliable setup in environments where technicians must install lenses quickly and accurately.
- Seamless integration with Panasonic DLP ecosystems: The ET-ELU20 is engineered to work harmoniously with Panasonic DLP projectors, supporting mounting ecosystems such as ET-EMU100/ELU20. Its mechanical precision ensures repeatable alignment, sturdiness under frequent use, and compatibility with the broader Panasonic projection lineup. By coupling this lens with compatible projectors, you gain a cohesive, optimized optical chain that preserves brightness, color fidelity, and image geometry across the entire system.
- Reliability, image quality, and long-term performance: The lens assembly uses high-quality optics with coatings designed to minimize reflections and flare, delivering bright, true-to-life colors with minimal distortion. The ET-ELU20's rugged construction withstands daily operation in busy environments, maintaining consistent focus and image alignment over time. Whether in education, corporate, or home cinema applications, the lens supports durable performance, easy maintenance, and sustained visual impact across a wide range of content and lighting conditions.

how to install Panasonic ET-ELU20
- Prepare the projector: Ensure your Panasonic DLP projector is powered off and cool, with the original lens in place or the appropriate mounting interface ready for the ET-ELU20.
- Attach the lens: Remove the current lens assembly if required, then align the ET-ELU20 with the projector’s lens mount. Secure with the appropriate fasteners, ensuring even tightening to avoid misalignment.
- Set the initial throw and focus: Position the projector at a distance that supports your desired image size, then adjust the varifocal zoom to reach the target width. Use the focus control to obtain a sharp, uniform image across the screen.
- Calibrate geometry: Power on the unit and perform basic alignment checks. Correct any keystone or trapezoidal distortion with the projector’s built-in geometry controls and verify edge-to-edge uniformity in brightness and color.
- Finalize setup: Recheck lens locks, verify stability of mounting, and conduct a brief test with representative content to confirm that the image maintains sharpness, brightness, and color accuracy across the screen.
Frequently asked questions
- Q: What makes the ET-ELU20 an ideal choice for tight spaces? A: Its ultra-short-throw design lets you project large images from a minimal distance, reducing shadow interference and enabling flexible placement in small rooms, classrooms, or compact home theaters without compromising image quality.
- Q: Can the ET-ELU20 be used with all Panasonic DLP projectors? A: The lens is engineered for compatibility with Panasonic DLP models that support ELU-series lenses and mounting options, including integration with ET-EMU100/ELU20 systems. Always verify specific model compatibility with your projector.
- Q: How does zero-offset zoom benefit installation? A: Zero-offset zoom maintains a stable image position relative to the projector center, reducing the need for extensive keystone correction and simplifying alignment, especially in room corners or when mounting on ceilings or walls.
- Q: What content environments benefit most from the ET-ELU20? A: Educational spaces, corporate meeting rooms, museums, and home theaters where quick setup, reliable performance, and large, bright images are crucial for impactful presentations and immersive viewing experiences.
