The Panasonic ET-D3QW300 is a high-performance, large-aperture zoom lens engineered for flagship large-venue projectors, specifically designed to deliver exceptional image clarity and brightness in demanding environments like concert tours, mega-churches, large auditoriums, and high-end rental applications. Its defining feature is a versatile 1.11-1.70:1 zoom ratio, which provides installation flexibility by allowing the projector to be placed at varying distances from the screen while filling a desired image size. This range helps system integrators overcome physical space constraints without compromising on light output. The lens incorporates precision-ground, multi-element glass optics with advanced coatings to minimize internal reflection and maximize light transmission, ensuring bright, vivid images with consistent edge-to-edge sharpness and minimal chromatic aberration, even when projecting at the massive resolutions required for modern 4K content.

Constructed with professional touring in mind, the lens features a robust metal housing built to withstand the rigors of transportation and frequent setup/teardown. It includes integrated manual controls for zoom, focus, and lens shift, allowing for fine-tuned calibration on-site. Compatibility with motorized versions of these adjustments is also typical, enabling remote setup and adjustment—a critical feature for installations where the projector is inaccessible. Designed to maintain the high lumen output and contrast of the high-end projectors it pairs with, the ET-D3QW300 is a crucial component for any large-scale visual installation where image quality, reliability, and setup flexibility are paramount. It transforms a powerful light engine into a versatile and precise visual tool capable of dominating large canvases with stunning detail.
