The Panasonic ET-DLE170 is a professional standard zoom lens engineered specifically for single-chip DLP projectors, delivering versatile installation capabilities for corporate boardrooms, lecture halls, houses of worship, and fixed installation environments. With a throw ratio ranging from 1.7 to 2.4:1 for WUXGA projectors (16:10 aspect ratio), this lens enables precise image sizing and placement across diverse room dimensions without relocating the projection unit. The focal length spans 25.6mm to 35.7mm with a bright aperture of f/1.7 to f/1.9, ensuring consistent light output and image quality throughout the 1.4x zoom range while maintaining exceptional optical performance for critical presentation applications.

Designed for demanding professional installations, the ET-DLE170 incorporates motorized zoom and focus capabilities for smooth remote adjustment, allowing operators to alter projection distances and image proportions effortlessly from a control room or via automation systems. Constructed with precision all-glass elements, the lens maintains edge-to-edge sharpness and high contrast while minimizing chromatic aberration, ensuring that the projector's light output is maximized with minimal drop-off across the entire zoom range. The compact housing measures 95 x 95 x 166 mm and weighs only 0.9 kg (2.0 lbs), making it notably lightweight and easy to install in professional projection systems.

The ET-DLE170 is compatible with an extensive range of Panasonic 1-chip DLP projectors, spanning multiple series including PT-DZ870, DZ770, DZ780, DW830, DW750, DX100, DX820, as well as PT-RZ970, RZ770, RZ660, RW930, RW730, RX110, and RCQ80 series. Depending on projector aspect ratio, the lens provides specific throw ratio variations: 1.8–2.5:1 for WXGA (16:10) projectors and 1.8–2.5:1 for XGA (4:3) projectors. This flexibility makes the ET-DLE170 an indispensable tool for AV professionals seeking optimal image quality and installation adaptability across diverse projection environments.
