Panasonic ET-DLE035 Ultra Short Throw Lens: Compatible with PT-FRZ580C, PT-FRZ680C, PT-FRZ99C

Panasonic Original Lens ET-DLE035 is a genuine optical accessory for Panasonic engineering projectors. It is an Ultra Short Throw lens with a throw ratio of 0.380:1 (fixed focus), designed for 0.67-inch 1DLP panels. The original compatibility list covers 30 projector models; simply verify your projector model and panel size before installation—no adapter rings needed. The value of an original lens isn't about extra rows of numbers in a spec sheet, but that it is factory-calibrated to the optical path and mount of that projector series: once installed, the image circle, edge illumination, and focus travel all match design values, so you don't need keystone correction to compensate for image quality.

1. Lens Specifications

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange focal distance, and mount type not shown in the spec table, please verify with us based on your projector model—ordering based on model similarity alone carries the risk of incompatibility.

2. Throw Ratio and Installation Distance Conversion

The throw ratio is the ratio of installation distance to image width. This original lens is fixed-focus (0.380:1 (fixed focus)), so the installation distance changes linearly with image size with no adjustment margin—it must be measured accurately before installation.

The above figures are the clear distance from the lens face to the screen, excluding rear ventilation and cabling space. Calculated for 16:10 aspect ratio; actual values are subject to on-site measurement and the original manufacturer's manual.

3. Compatible Models (30)

The table below is taken from the original manufacturer's compatibility list; brightness and resolution are filled in from the model database, with "—" where unavailable—no speculation.

For models not on the list, please send us photos of the projector nameplate and the existing lens for verification—same-generation platforms often share the same mount, but ordering based on model similarity alone is not worth the risk.

Throw Ratios Across Different Model Series

The same ET-DLE035 installed on the following series has different nominal throw ratios; selection should be based on the actual projector series.

4. Three Things to Confirm Before Replacement

• Panel size must match. The ET-DLE035 is designed for 0.67-inch 1DLP panels. Projectors with different panel sizes or resolutions may physically mount, but the image circle and edge illumination will be compromised.
• Calculate installation distance first. This lens has a nominal throw ratio of 0.380:1 (fixed focus); use the table in Section 2 to match your venue dimensions. Fixed focus has no margin, and even zoom lenses should allow 10–20 cm at both ends.
• Check the mount and locking mechanism. The original lens is calibrated to the projector series mount; after installation, you must hear the lock click into place. Image skew and soft edges are usually caused by incomplete locking, not the lens itself.

If unsure, take a photo of the projector nameplate and the existing lens nameplate and send them to us—verification against the actual hardware is the most reliable approach.
