FA103 Projector Lens for 2 Sonoke Models: SNP-LU21K, SNP-LU18K

FA103 is a medium-to-long focal length lens for engineering projectors (Sony). It is compatible with 2 projector models from 1 model series. This guide presents the lens specifications, throw distance, model compatibility list, and replacement considerations in one place.

1. Lens Specifications

2. Throw Distance

The throw ratio for this model has not yet been included in our database. For the throw distance, refer to the nameplate on the actual projector and the user manual, or contact us to calculate it based on the on-site dimensions.

3. Compatible Projector Models (2 Models, Sony)

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

4. Three Checks Before Replacement

• Verify the panel dimensions. Panel specifications for this model have not yet been included in our database. Please send us a photo of the projector’s nameplate so we can confirm them.
• Check the interfaces and locking mechanism. Interfaces are generally compatible across platforms of the same generation, but the locking tab position varies between generations. If the image appears skewed or its edges look soft after installation, the locking tab is usually not fully engaged; this is generally not a problem with the lens itself.
• A fixed-focus lens has no zoom adjustment. Image size can only be changed by moving the projector, so the site dimensions must be measured accurately first, with an additional 10–20 cm allowed at each endpoint.

For models outside the list, it is safer to send us photos of the projector nameplate and original lens for verification. Platforms of the same generation often share the same interface, but ordering based solely on a similar model number carries risks that are not worth taking.
