VPLL-Z3024 Projector Lens 1.94–3.1:1 for 16 Sony Professional Projectors

VPLL-Z3024 is a medium-to-long-throw lens for Sony professional projectors, with a throw ratio of 1.94–3.1:1. It is compatible with 16 projector models in 1 model series. This guide compiles the lens specifications, installation distances, model compatibility list, and key replacement considerations in one place.

1. Lens Specifications

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This is a zoom lens (1.94–3.1:1), so each image size corresponds to a range of distances, and the lens can be focused at any installation distance within that range.

These figures are the clear distance from the front surface of the lens to the screen and do not include clearance behind the projector for cooling and cable connections. They are calculated for a 16:10 image; verify actual distances on site and against the manual.

Image quality differs at the two ends of the zoom range: near the short-throw end, the image is brighter and the edges are slightly softer; near the long-throw end, the edges are sharper and brightness decreases slightly. 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—adjusting both at the same time makes precise alignment difficult.

3. Compatible Models (16 Models, Sony)

The table below is arranged by model release date, from newest to oldest, and includes each model's resolution, brightness, and standard lens zoom ratio for quick identification based on project requirements.

The zoom ratio is the zoom factor of the factory-supplied standard lens for each model (upper limit ÷ lower limit of its throw-ratio range), not the zoom range of the lens discussed in this article.

Common Features of These Models

The factory-supplied standard lenses for these 16 models mostly fall within a throw ratio of 1.39:1-2.23:1. The 1.94–3.1:1 ratio of the model featured here effectively extends the focal range, enabling 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 Checks Before Replacement

• Check the panel size. Panel specifications for this model have not yet been added to our database. Please send us a photo of the projector nameplate for confirmation.
• Check the interface and locking mechanism. Interfaces are generally interchangeable across platforms of the same generation, but the locking latch positions vary by generation. If the image appears skewed or the edges are not sharp after installation, the most likely cause is incomplete locking rather than a problem with the lens itself.
• Allow extra zoom margin. When measuring the distance, allow an additional 10–20 cm beyond the range endpoints, as transportation and installation variations may push the lens outside its usable range.

For compatibility with models not on the list, it is safer to send us the projector nameplate and a photo of the original lens for verification—platforms of the same generation often share the same interface, but ordering based on a similar model designation carries unnecessary risk.
