PRODUCT OVERVIEW

Panasonic ET-EMW400 Zoom Lens

The Panasonic ET-EMW400 is a high-precision interchangeable zoom lens designed for Panasonic’s professional 3LCD laser projector series, including the PT-MZ20, PT-MZ17, PT-MZ16, PT-MZ13, and PT-MZ10 models. It is engineered to deliver flexible projection distances while maintaining exceptional optical clarity, making it ideal for large venues, corporate environments, higher education institutions, and immersive display installations. With its robust mechanical and optical design, the lens ensures consistent image quality across a wide range of installation scenarios.

Optical Performance and Throw Ratio Flexibility

This lens provides a short-throw zoom range of 0.690–0.950:1, enabling large images to be projected even in tight or constrained spaces. It supports multiple aspect ratios, including 16:10, 16:9, and 4:3, ensuring compatibility with diverse content formats. The optical system is designed to minimize distortion while preserving sharpness and brightness uniformity across the entire projection surface, which is critical for professional AV presentations and projection mapping applications.

Precision Engineering and Optical Design

The ET-EMW400 features a focal length range of 15.3 mm to 21.1 mm and a fast aperture of f/1.84–2.24, allowing efficient light transmission and strong image brightness performance even at wider throw angles. Its precision-engineered glass elements ensure minimal chromatic aberration and high-resolution image reproduction when paired with Panasonic’s high-lumen laser projectors. This makes it particularly suitable for environments requiring high visual fidelity, such as museums, control rooms, and simulation centers.

Installation Compatibility and Practical Use

Designed for seamless integration, the ET-EMW400 supports quick installation and secure mounting on compatible Panasonic projector bodies. Its mechanical structure allows fine adjustment of focus and zoom, ensuring accurate alignment in professional installations. Weighing approximately 5.05 kg, it is built with durability in mind while maintaining smooth operational adjustment. The lens is optimized for stable long-term use in fixed installations where reliability and minimal maintenance are critical requirements.
