Panasonic ET-ELS20 1.7 - 2.8:1 fixed zoom lens for PT-MZ880/MZ770/MZ670 Series, PT-EZ770 Series, PT-EZ580 Series and PT-EZ570 Series projectors

Product Overview

The Panasonic ET-ELS20 is a 1.7–2.8:1 fixed zoom lens engineered for Panasonic PT-MZ880, PT-MZ770, PT-MZ670, PT-EZ770, PT-EZ580, and PT-EZ570 series commercial projectors. This standard-to-long-throw projector lens lets an AV integrator position the projector well back from the screen, which makes it a practical interchangeable lens for large conference rooms, auditoriums, and houses of worship. As a factory lens option, it preserves the host projector's optical alignment and image geometry across its zoom range.

Product Description

The ET-ELS20 covers a throw ratio of 1.7 to 2.8:1, giving designers room to fine-tune image size during commissioning without relocating a ceiling-mounted or rack-adjacent projector. By varying the focal distance, the lens adapts a single projector chassis to different screen sizes and mounting depths, which is useful when standardizing on one projector model across rooms of varying dimensions. It is intended strictly for the supported 1-chip LCD models and is not cross-compatible with other lens families.

For shorter mounting distances on the same projector series, consider the Panasonic ET-ELW20 (1.3–1.7:1) lens. For longer throws in deeper rooms, the ET-ELT22 (2.7–4.5:1) and ET-ELT23 (4.4–7.1:1) lenses extend the same platform, letting integrators standardize on one projector while matching the lens to each room.

Key Features

• 1.7–2.8:1 Zoom Range — Covers standard to long throw distances so one lens serves a range of room depths without moving the projector.
• Native Panasonic Compatibility — Designed for PT-MZ880, MZ770, MZ670, EZ770, EZ580, and EZ570 series chassis for a predictable fit and consistent image alignment.
• f/1.7–2.3 Aperture — Holds brightness across the zoom range for consistent on-screen luminance in commercial meeting spaces.
• 26.9–45.4mm Focal Length — Provides image-size flexibility during commissioning and future screen changes.
• Interchangeable Lens Design — Installs into the lens mount of supported projectors, allowing a field swap without replacing the projector.
• Lightweight 0.9 kg Build — Eases handling during staging and service of ceiling-mounted projectors.

Typical Applications

• Auditorium — Long-throw zoom suits deep rooms where the projector mounts far from a large screen.
• House of Worship — Matches projector placement to sanctuary depth for large-format image delivery.
• Conference Room — Adapts a standardized projector to larger meeting rooms with longer throw distances.
• Training Room — Sizes the image to the screen from a rear or recessed mounting position.
• Multi-Purpose Room — Accommodates flexible seating layouts and variable projector placement.

Frequently Asked Questions

Which projectors is the ET-ELS20 compatible with?
It is designed for the Panasonic PT-MZ880/MZ770/MZ670, PT-EZ770, PT-EZ580, and PT-EZ570 series. Confirm your exact model against Panasonic's lens compatibility chart before ordering.

What throw distance does the 1.7–2.8:1 ratio give me?
Multiply your screen width by the throw ratio to estimate projector distance. For a 10 ft wide image, that is roughly 17 to 28 ft, which suits larger rooms and auditoriums.

Can I install this lens in the field?
Yes. As an interchangeable lens it mounts to the supported projector on site. Follow Panasonic's lens installation and calibration procedure after fitting.

Is this lens covered by warranty?
Panasonic Pro AV optical accessories carry the manufacturer's warranty. Contact Creation Networks for current warranty terms and extended coverage options.
