WE292 Lens 0.5–0.6:1 for 13 Sony Models: SNP-ELU100 ELU840 ELU740 ELU640 LU16KC LU13KC U100L U80L

WE292 is a short-throw lens for the 0.65/0.66/0.67-inch panel group (Sonoco), with a 0.5–0.6:1 throw ratio and lens shift. It is compatible with 13 projector models across 2 model series. This guide presents the lens specifications, installation distances, model compatibility list, and replacement considerations in one place.

1. Lens Specifications

Lens-shift capability is the key differentiator of this lens. A shift range of ±35% horizontally and ±10% vertically allows the projector to be installed off the screen’s central axis, with lens shift bringing the image back into position without requiring keystone correction. Keystone correction comes at a cost—each adjustment step reduces the effective pixel count and makes text edges appear blurry. In professional installations, lens shift should always be used instead of keystone correction whenever possible; preserving image quality is the bottom line.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This lens has a zoom range of 0.5–0.6:1, so a range of installation distances corresponds to any given image size. The lens can be focused at any distance within the applicable range.

The above values represent the clear distance from the front surface of the lens to the screen and do not include space for rear cooling and cable connections. These calculations are based on a 16:10 image; actual distances should be verified through on-site measurements and the manual.

Image quality differs at the two ends of the zoom range: near the short end, the image is brighter and the edges are slightly softer; near the long end, the edges are sharper and the brightness is slightly lower. Where site conditions allow, use the middle of the range. After installation, first find the sharpest position using the focus ring, then fine-tune the lens shift—optimizing both variables at the same time makes precise alignment difficult.

3. Compatible Projector Models (13 Models, Sonoco)

The following table is arranged by model production date from newest to oldest and includes each model’s resolution, brightness, and zoom ratio for its original standard lens, enabling quick identification according to project requirements.

The zoom ratio is the zoom factor of the model’s original standard lens (upper limit ÷ lower limit of its original throw-ratio range), not the zoom range of the lens featured in this article.

Common Features Across These Models

The original standard lenses for these 13 models generally have throw ratios clustered around 1.22-1.52：1. The 0.5–0.6:1 model featured in this article effectively changes the focal-length range, allowing the same projection distance to produce a different image size—this is the direct reason for replacing the lens. It also retains full lens-shift capability, allowing the image to be realigned after the focal range is adjusted.

4. Three Checks Before Replacing the Lens

• Panel size and resolution must match. This model is compatible with 0.67-inch panels. Projectors with different panel sizes or resolutions will vary somewhat in projection performance, so it is safest to verify the chassis nameplate before installation.
• Interfaces and locking mechanism. Interfaces are generally compatible within the same platform generation, but locking-latch positions vary by generation. If the image is skewed or the edges are not sharp after installation, the latch is usually not fully engaged rather than the lens itself being faulty.
• Lens-shift allowance must be included in installation planning. The shift range provides some installation flexibility, but edge image quality declines at the limits, so actual use should be kept within 70% of the specified values.

For compatibility with a model not listed, it is safer to send us a photo of the chassis nameplate and the original lens for verification—although models from the same platform generation often share interfaces, the risk of ordering based solely on a similar model designation is not worth taking.
