Panasonic ET-C1U200 Ultra Short Throw Lens: Compatible with 16 Models Including PT-REQ15C PT-REQ12C

Panasonic Original Lens ET-C1U200 is a genuine optical accessory for Panasonic professional projectors. It is an ultra short throw lens with a throw ratio of 0.380:1 (fixed focus), designed for 0.8" 1DLP panels. The original compatibility list covers 16 projector models; simply verify against the projector model and panel size before installation—no adapter rings needed. The value of an original lens isn't about a few extra rows in the spec sheet, but that it is calibrated at the factory to the optical path and bayonet of that projector series: once mounted, 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 bayonet type not shown in the spec table, please verify with us against your projector model—ordering based on model similarity alone carries the risk of incompatibility.

2. Converting Throw Ratio to Installation Distance

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—measure accurately before installation.

The above are clear distances 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 (16)

The table below is taken from the original 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 bayonets, but ordering based on model similarity alone isn't worth the risk.

Throw Ratios Across Model Series

The same ET-C1U200 mounted on the following series does not have the same nominal throw ratio; selection should be based on the actual projector series.

4. Three Things to Confirm Before Replacement

• Panel size must match. The ET-C1U200 is designed for 0.8" 1DLP panels. Projectors with different panel sizes or resolutions may physically mount, but the image circle and edge illumination will suffer.
• Calculate installation distance first. This lens has a nominal throw ratio of 0.380:1 (fixed focus); apply the table in Section 2 to your venue dimensions. Fixed focus has no margin; even for zoom lenses, leave 10–20 cm at both ends.
• Check the bayonet and locking. Original lenses are calibrated to the projector series bayonet; you must hear the lock engage after mounting. 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 safest approach.
