The Panasonic ET-D75LE6 is a high-performance, short-throw zoom lens designed for use with Panasonic's extensive line of 3-Chip DLP projectors. This powered lens provides installers with the flexibility to achieve large images from a short projection distance, which is particularly beneficial in environments with limited space, such as some rear projection installations or auditoriums. Its zoom functionality allows for a variety of throw distances while maintaining image consistency, and both the zoom and focus can be adjusted remotely (via the projector's own motorized controls) for ease of setup and fine-tuning.

The lens is built with professional-grade optics, featuring an F value of 2.5 and a focal length range of 19.63 to 23.54 mm. The key feature is its variable throw ratio, which is dependent on the aspect ratio of the connected projector. For WUXGA (16:10 aspect ratio) projectors, the throw ratio is approximately 0.924–1.10:1. This versatility ensures that the lens can be matched to different models in Panasonic's professional lineup, from the PT-DZ21K series to the PT-RQ13K series and beyond.

Physically, the ET-D75LE6 is a substantial accessory, weighing approximately 8.7 kg (19.2 lbs). Its robust construction and precise engineering ensure reliable performance in demanding professional audiovisual environments. The ability to produce large, high-resolution images while positioned close to the screen makes it an essential component for high-end installations where flexibility and image quality are paramount.
