Panasonic ET-EMW400 15.3-21.1mm Zoom Lens

Overview

The Panasonic ET-EMW400 is a zoom lens designed specifically for PT-MZ16K, PT-MZ13K, and PT-MZ10K LCD laser projectors, enabling users to project large images from short distances. With a focal length range of 15.3 mm to 21.1 mm, it allows for flexible placement closer to the screen while still covering wide image sizes. This lens is ideal for environments where space is limited, such as classrooms, conference rooms, museums, and rental stages.

Its throw ratio ranges from 0.69 to 0.95 to 1 for widescreen formats (16:10 and 16:9), allowing a 100-inch image to be projected from about 5 to 7 feet away. For 4:3 content, the throw ratio adjusts to 0.83 to 1.15 to 1, providing versatility across different screen formats. The motorized zoom and focus system simplifies adjustments after installation, preserving the projector’s brightness and image clarity.

Key features
