ET-ELW20 Compatible Projector Model List (14 models total, with brightness/resolution)

The following are verified compatible models for the ET-ELW20, each listed with brightness and resolution. The compatible lens model for all is ET-ELW20:

Note: Brightness/resolution data is sourced from the model database (refer to the machine's nameplate/manual for accuracy). Lens compatibility is based on the machine's lens mount and panel/chip size. For models not on this list, please contact Zorsika technical support for confirmation.

About This Original Lens

The ET-ELW20 is a Standard Throw lens produced by Panasonic. Its optical structure, lens coatings, and mechanical tolerances are matched to the original projector specifications, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., projecting a large image from a short distance, ultra-short throw close to the wall), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 1.21-1.66:1. Throw Ratio = Projection Distance ÷ Image Width: a smaller value produces a larger image (suitable for close distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the on-site installation distance and screen size, then match it to this model.

Authenticity and Procurement Information

Zorsika supplies the authentic Panasonic original lens ET-ELW20 through authorized channels, complete with original packaging and a verifiable serial number. It is suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and other applications.

• Authenticity Guarantee: Sourced through official manufacturer channels, with original packaging and serial number. For bulk projects, channel credentials can be provided upon request to eliminate refurbished units or sources of unknown origin.
• Compatibility Verification: Provide the machine model before ordering. Zorsika technical support will verify it against the compatible model list above to avoid installation issues.
• Project Supply: The ET-ELW20 covers 14 models. For frequently used projects, schedule in advance to shorten lead times.
• Alternative Solutions: If budget is a concern, Zorsika can also provide alternative lenses with the same specifications. Key parameters are benchmarked against the original; choose as needed.

Note: Actual imaging performance is affected by the machine's condition and installation environment. For large bulk orders, it is recommended to first obtain one unit for testing.

Frequently Asked Questions

Q: How to choose between an original lens and an alternative lens?

A: Original lenses are manufactured by Panasonic, with optical parameters and mechanical tolerances calibrated to the original machine, suitable for projects with strict requirements for OEM consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount benchmarked against the original, offering advantages in budget and lead time. Zorsika can supply both lines; choose based on project requirements.

Q: How can I confirm this lens will work with my machine?

A: Compatibility is based on the machine's lens mount and panel/chip size. This article lists verified compatible models. Engineering projectors of the same generation and brand often share mounts. If unsure, it is safer to take a photo of the machine's nameplate and send it to Zorsika technical support for confirmation.

Q: How to choose the throw ratio?

A: Throw Ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short/ultra-short throw is suitable for close distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the installation distance and screen size, then match it to the focal range of this model.

Q: How can I ensure the ET-ELW20 is authentic?

A: Zorsika supplies authentic products through official manufacturer channels, complete with original packaging and a verifiable serial number. For bulk projects, channel credentials can be provided upon request to ensure the units are not refurbished or second-hand.

Q: What should I pay attention to when replacing a lens?

A: Before disassembly, be sure to power off the machine and wait for the cooling fan to stop. Hold the lens by the barrel, avoiding contact with the lens elements. Use a blower to gently remove any dust. After installation, perform a focus test before tightening the mounting screws, and take the opportunity to clean the mount and contacts.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (such as impact, water ingress, or unauthorized disassembly), contact after-sales service directly. The warranty period is based on the date on the shipping documents.
