Panasonic ET-C1W300

Wide Zoom Lens for Unmatched Performance and Versatility

The ET-C1W300 is a wide zoom lens with a throw ratio of 0.550–0.690:1. It is part of the C1 series of aspherical glass lenses, designed specifically for Panasonic's PT-REZ15 and PT-REQ15 series of projectors (and future 1-Chip DLP™ projectors). These lenses enhance the quality of immersive experiences while streamlining workflow and resource management.

The ET-C1W300 expands your creative vision by delivering breathtaking visuals. Ultra Extra-low Dispersion (UED) glass and proprietary AR coatings correct aberration, boost native contrast, and improve color uniformity for high visual impact. C1 lenses also feature Lens Memory and Auto Lens Identification functions.

New features such as an expanded powered lens shift range, powered peripheral focus function, and wider zoom ratios enhance flexibility and workflow efficiency, adapting projections to diverse spaces and reducing lens inventory overheads.

Compatible projectors ensure imaging stability with a strengthened lens mounter structure, while durable, heat-resistant lens materials extend longevity and reduce the need for periodic focus adjustment, maintaining image quality in long-term settings.

Note: Please check the Compatibility tab to make sure that this lens is compatible with your projector.

These features apply to all lenses from the C1 series, except where noted.

Bring Out the Best in Your Visuals

• UED Glass for Flawless Image Quality: Panasonic’s C1 Series use precision-ground Ultra Extra-low Dispersion (UED) glass lens elements¹ to minimize light scattering, a common cause of flare and color blur. The lens produces sharp, uniform visuals with realistic contrast and color performance.

• Dramatically Improved Native Contrast Performance: Precision UED glass lens elements¹ improve native contrast performance by as much as 16%² over equivalent lenses in the DLE Series. Combined with the projector’s evolved Dynamic Contrast technology, this enhancement ensures that high-quality content is faithfully reproduced, drawing guests deeper into your experience.

• Proprietary AR Coating for Exceptional Uniformity: Reflections from the lens surface and internal reflections can cause color irregularities and ghosting on the screen, degrading color uniformity. The C1 Series employs a proprietary Anti-Reflection (AR) coating to prevent diffuse light reflection, depositing a thin film on the lens surface to reduce color irregularities and ghosting. The coating is particularly important for maintaining color uniformity with ultra-short-throw lenses: the ET-C1U100 leverages Panasonic’s accumulated expertise in AR coating development, contributing to outstanding color uniformity.

• Aspherical Lenses: Superior Imaging, Compact Design: The ET-C1U100, ET-C1U200³, ET-C1W300, ET-C1W400, and ET-C1W500 feature aspherical glass lens elements. Aspherical glass achieves the same effect as multiple lens elements, enabling high magnification power and reducing size and weight. Aspherical lens manufacturing demands extreme precision and expertise. Panasonic answers with accumulated know-how, producing the ET-C1U100’s large-diameter elements at a state-of-the-art facility in Yamagata, Japan, to ensure spectacular visuals in an easy-to-handle form factor.

Enhanced Workflow Efficiency

• Outstanding Flexibility with a Wider Shift Range: Enjoy an expanded range of powered lens shift adjustments via remote control, and adapt projections to diverse production spaces. For example, the ET-C1U100 Ultra-Short-Throw Zoom Lens boasts a significantly wider shift than the ET-DLE020 with a ±50% vertical and ±23% horizontal adjustment range. You can easily adjust the image position to suit your spatial design in tight spaces, when the projector isn't in an ideal location.

• Powered Peripheral Focus: A First for Panasonic 1-Chip DLP™ Lenses: The C1 Series introduces powered peripheral focus⁴, a first for Panasonic’s 1-Chip DLP™ projection lenses. Maintaining edge-to-edge focus is vital for immersive entertainment where large images are viewed at close range. Users can now adjust zoom⁵, center focus, peripheral focus⁴, and lens shift via remote control or Smart Projector Control app⁶, eliminating the need for physical access to the projector in hard-to-reach locations. This streamlines operations and gives you the power to achieve professional results efficiently.

• Wider Zoom Ratios Streamline Your Inventory: Zoom lenses in the C1 Series feature wider zoom ratios than DLE Series lenses, enabling rental and staging companies to maintain smaller inventories while meeting diverse project requirements. This wider coverage reduces overheads and streamlines operations, making the C1 Series a more efficient, cost-effective, and eco-friendly solution for rental businesses. (Note: The ET-C1U200 does not have zoom).

• Larger Screens, Fewer Projectors, Smaller Footprint: Unlock larger screen sizes up to 1000 inches and use fewer projectors to cover the display area while reducing costs, installation complexity, and environmental impact. For example, a 1000-inch diagonal screen that previously required two projectors can now be covered by a single projector fitted with an appropriate C1 Series lens, contributing to enhanced sustainability through decreased resource consumption and carbon footprint.

  

Consistently Stable Image Quality

• Robust Lens Mounter Improves Stability: Projectors compatible with the C1 Series feature a revised lens mounter structure that strengthens vibration resistance, reducing the need for periodic focus adjustments. The labor-saving design also simplifies the installation of ultra-short-throw zoom lenses. Previously, an optional bracket was necessary for this lens type, which restricted the shifting range. The updated structure, complete with a hex-head screw kit, allows for bracket-free installation of the ET-C1U100, saving time and resources.

• Rugged Design Maintains Stable Image Quality: The C1 Series employs glass lens elements for durability in rental situations or for touring productions where lenses are frequently handled. Stable imaging is ensured by selecting heat-resistant materials less prone to aberrations resulting from temperature fluctuations. Proprietary simulation models temperature rises in the lens due to light exposure, allowing the best selection of materials to resist focus drift and reduce maintenance.

Other Features

• Compatible with Auto Lens ID function, automatically adjusting the projection method to suit specific lenses

• Lens Memory Function saves zoom/focus/shift data sets to enable rapid switching between various projection planes

• Compatible with the Smart Projector Control app⁶, enabling focus adjustments via the device camera⁷ and easy access to Lens Control UI settings
