WF205 Projector Lens 0.5:1 for Sharp XG-TK506ZS and TK500ZS

WF205 is a short-throw lens for the 0.65/0.66/0.67-inch panel group (Sharp), with a 0.5:1 throw ratio. It is compatible with 2 projector models in 1 model series. The lens specifications, installation distances, model compatibility list, and replacement considerations are summarized below.

1. Lens Specifications

2. Installation Distance Calculation by Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This lens has a fixed focal length (0.5:1), so the installation distance varies linearly with image size, leaving no room for adjustment. Accurate measurements are essential before installation.

The distances above are clear measurements from the front of the lens to the screen and do not include space for rear housing ventilation or cable connections. The values are calculated based on a 16:10 image; actual on-site measurements and the manual take precedence.

3. Compatible Models (2 Models, Sharp)

The table below is arranged from newest to oldest by model production date. It includes the resolution, brightness, and factory lens zoom ratio for each model, making it easy to identify the right option for your project.

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

Common Features of These Models

The factory-standard lenses for both models typically have throw ratios around 0.8:1. The 0.5:1 ratio of the model discussed here effectively adjusts the focal range, allowing different image sizes at the same projection distance—this is the direct reason for replacing the lens. Full lens-shift capability is retained, so the image can still be aligned after adjusting the focal range.

4. Three Things to Confirm Before Replacement

• The panel and resolution must match. This model is compatible with a 0.65-inch panel. Projectors with a different panel size or resolution may produce somewhat different projection performance, so checking the nameplate on the projector before installation is the safest approach.
• Check the interface and locking mechanism. Interfaces are generally shared within the same platform generation, but the position of the locking latch differs between generations. If the image appears skewed or the edges are unclear after installation, the latch is usually not fully engaged rather than the lens itself being faulty.
• A fixed-focus lens has no zoom adjustment. The image size can only be changed by moving the projector, so the site dimensions must be measured accurately, with an additional 10–20 cm allowed at both ends of the mounting range.

For models not on the list, the safest approach is to send us a photo of the projector nameplate and the original lens for verification—platforms from the same generation often share the same interface, but ordering based on a similar model number is not worth the risk.
