Sony VPLL-Z3024 Long-Throw Lens for VPL-F755HZ, VPL-F750HZ, VPL-F655HZ, VPL-F630WZ, VPL-F436HZ

Sony Genuine Lens VPLL-Z3024 is an OEM optical accessory for Sony professional projectors. It is a long-throw (Long Throw) lens with a throw ratio of 2.34-3.19:1 for Z3-series-inch panels. The OEM compatibility list covers 5 models; before installation, simply verify the projector model and panel size—no adapter rings are needed. The value of an OEM lens lies not in the extra figures in its specifications, but in its factory calibration to the optical path and mount of that projector series: once installed, the image circle, edge illumination, and focus travel are all at their design values, with no need for keystone correction to compensate for image quality.

I. Lens Specifications

The above specifications are subject to the OEM specifications. For mechanical dimensions, flange distance, and mount type not shown in the specifications, please contact us with the projector model. Ordering based solely on a similar model carries the risk that the lens will not fit.

II. Converting Throw Ratio to Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This OEM lens is a zoom lens (2.34-3.19:1), so a given image size corresponds to a range of installation distances, and it can focus at any distance within that range.

These figures represent the clear distance from the front of the lens to the screen and do not include space required for rear ventilation and cable connections. They are calculated for a 16:10 image; actual distances are subject to on-site measurements and the OEM manual.

Image quality differs at the two ends of the zoom range: the image is brighter and the edges are slightly softer at the close end, while the edges are sharper and brightness is slightly lower at the far end. Where the venue allows, the middle of the range is recommended. After installation, first find the sharpest setting on the focus ring, then fine-tune the lens shift.

III. Compatible Models (5 Models)

The table below is taken from the OEM compatibility list. Brightness and resolution are populated from the model database; unavailable entries are marked “—” and are not estimated.

To check whether a model outside the list can be used, send us photos of the projector nameplate and the existing lens. Same-generation platforms often share mounts, but ordering based on a similar model carries unnecessary risk.

Throw Ratio by Model Series

The nominal throw ratio varies when the same VPLL-Z3024 lens is installed on the series listed below. Select the value according to the series of the actual projector.

IV. Three Checks Before Replacement

• The panel size must match. VPLL-Z3024 is designed for Z3-series-inch panels. Even if the lens fits the mount, a projector with a different panel size or resolution may experience problems with the image circle and edge illumination.
• Calculate the installation distance first. This lens has a nominal throw ratio of 2.34-3.19:1. Use the table in Section II to match the dimensions of your venue. A fixed-focus lens offers no adjustment margin, and even a zoom lens requires 10–20 cm of margin at both ends.
• Verify the mount and locking mechanism. The OEM lens is calibrated to the mount of that projector series. You must hear it lock into place after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a problem with the lens itself.

If you are unsure, photograph the projector nameplate and the existing lens nameplate and send them to us. Verification against the actual products is the most reliable approach.
