The Panasonic ET-EMU100 is a premium ultra-short throw zoom lens engineered to simplify projector installation while delivering immersive, edge-to-edge image quality. Designed for DLP projectors, this zero-offset lens redefines ceiling-to-wall alignment, enabling clean, unobstructed setups even in tight spaces. With a versatile 7.23 mm to 7.73 mm focal length range and a fast f/1.9 aperture, the ET-EMU100 balances brightness, detail, and throw flexibility for classrooms, conference rooms, and home theater environments alike. Whether you’re upgrading an existing ultra-short throw system or building a new projection solution, this lens offers robust performance, streamlined installation, and reliable optical quality that Panasonic is known for.

• Ultra-short throw versatility: The ET-EMU100 provides a flexible focal length range of 7.23 mm to 7.73 mm, enabling expansive screen sizes from very short throwing distances. This makes it ideal for tight rooms where traditional lens setups would require excessive space, while still delivering a large, immersive image with minimal throw distance.
• Zero-offset design for effortless installation: Engineered with zero-offset optics, this lens aligns the projector’s optical axis with the image, simplifying alignment and minimizing keystone correction. The result is a cleaner, faster installation that reduces the need for frequent adjustments and contributes to a more reliable, long-term projection setup.
• Bright f/1.9 aperture for compelling images: The fast maximum aperture enhances brightness and contrast, helping to maintain vivid image quality in a variety of lighting conditions. This makes the ET-EMU100 suitable for both well-lit environments and controlled dark-room spaces, preserving detail in shadows and highlights alike.
• Designed for DLP projectors: Built to complement DLP projector systems, the ET-EMU100 delivers optimized optical performance for ultra-short-throw configurations. Its precision-engineered elements maximize sharpness, reduce distortion, and deliver consistent color accuracy across the screen.
• Compact, durable construction and easy maintenance: The lens is designed for reliable daily use, with a compact footprint that minimizes space requirements and simplifies handling. Its rugged build supports frequent adjustments in busy environments and supports long-term maintenance without sacrificing performance.

how to install Panasonic ET-EMU100

• Step 1: Power off and unplug the projector from the power source. Allow the system to cool before handling the lens interface.
• Step 2: If removing a current lens, carefully detach it from the projector’s lens mount following the manufacturer’s safety guidelines. Place any screws or mounting hardware in a secure location.
• Step 3: Align the ET-EMU100 with the projector’s lens mount, ensuring the lens locking alignment marks are matched to the corresponding mounts on the projector. Gently slide the lens into place.
• Step 4: Secure the lens using the projector’s locking mechanism or mounting screws, as specified by the model’s installation manual. Confirm a firm, stable fit without forcing components.
• Step 5: Power on the projector and perform initial focus, zoom, and alignment adjustments. Use the throw distance to position the image on screen, then fine-tune focus and keystone as needed. For best results, run any automatic lens calibration or optical alignment routines provided by the projector, and reference the ET-EMU100 user guide for model-specific instructions.

Frequently asked questions

• Q: What makes the ET-EMU100 an ultra-short throw lens?

  A: The ET-EMU100 is purpose-built for ultra-short throw projection, delivering a large image from a very short distance. Its zero-offset design aligns the optical axis with the screen, reducing installation complexity and helping to minimize distortion and keystone issues commonly encountered in tight spaces.

• Q: Which projectors work with the ET-EMU100?

  A: This lens is designed for Panasonic DLP projectors that support ultra-short throw zoom lenses. Always check compatibility with your specific model's lens mount and throw requirements in the official documentation or with Panasonic support before purchasing.

• Q: How does the zero-offset design benefit installation?

  A: Zero-offset lenses place the focal axis in line with the projector’s optical center, simplifying mounting geometry and reducing the need for extensive keystone correction. This yields easier alignment, faster setup, and a cleaner image without skewed geometry.

• Q: Can I adjust image size and position with the ET-EMU100?

  A: Yes. The 7.23–7.73 mm focal length range provides flexibility to fit various screen sizes and room layouts. Use the projector’s zoom, focus, and any lens shift or keystone controls in combination with the ET-EMU100 to achieve the desired image size and position.

• Q: What maintenance or care does the ET-EMU100 require?

  A: Regular handling with care, keeping the lens clean from dust and fingerprints, is recommended. Use a soft microfiber cloth for external surfaces and follow the projector’s maintenance guidelines for internal optics. If the lens becomes misaligned, contact Panasonic support or a qualified technician for recalibration.
