Panasonic ET-ELS20 1.7-2.8:1 Zoom Lens

The Panasonic ET-ELS20 is a zoom lens designed for installers and presenters who need flexible image placement with compatible PT-EZ570, PT-EZ580, and PT-EZ770Z projectors. By shifting the throw ratio between 1.7:1 and 2.8:1, it lets you fine-tune screen size from different mounting distances, a benefit in classrooms, corporate boardrooms, houses of worship, or exhibition spaces where ceiling height and seating layouts can vary.

The focal length moves from 26.9 mm to 45.4 mm, giving you the freedom to adjust projection distance without relocating the projector. An f/1.7 to f/2.3 aperture range helps preserve brightness, so images stay clear even when you install farther from the screen. Because the lens weighs only 0.9 kg and seats directly into the projector without adapters, swap-outs during maintenance or event changeovers are quick and secure.

Integrators will appreciate how the ET-ELS20 supports edge blending, stacking, and other advanced setups that depend on accurate lens alignment. In multi-projector arrays or single-unit installations, it delivers uniform focus across the image, easing the task of creating professional presentations in medium-sized conference rooms or large auditoriums.
