Sony VPLL-Z4107 Standard Throw Lens Guide for VPL-F905ZL, VPL-F1306ZL, VPL-F1006ZL, VPL-F906ZL

Sony Genuine Lens VPLL-Z4107 is an original optical accessory for Sony engineering projectors. It features a standard throw (Standard Throw), a throw ratio of 0.75-0.94:1, and is designed for 4-series-inch panels. The factory compatibility list covers 4 models; simply verify the projector model and panel size before installation—no adapter ring workaround is needed. The value of a genuine lens lies not in extra rows of specifications, but in the fact that it is calibrated at the factory to the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focus travel all meet the design specifications, so there is no need to use keystone correction to compensate for image quality.

I. Lens Specifications

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

II. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of installation distance to image width. This genuine lens is a zoom lens (0.75-0.94:1), so a given image size corresponds to a range of distances. It can be focused at any position within that range during installation.

These figures represent the clear distance from the front of the lens to the screen and do not include space required for rear cooling and cable connections. They are calculated for a 16:10 image; actual distances should be verified through on-site measurement and the manufacturer's manual.

Image quality differs at the two ends of the zoom range: toward the short-throw end, the image is brighter and the edges are slightly softer; toward the long-throw end, the edges are sharper and the brightness is slightly lower. Where the venue allows, aim for the middle of the range. After installation, find the sharpest position using the focus ring, then fine-tune the lens shift.

III. Compatible Models (4 Models)

The following table is taken from the manufacturer's official compatibility list. Brightness and resolution have been populated from the model database; entries that could not be obtained are shown as —, with no assumptions made.

To confirm compatibility with a model outside this list, send us photos of the projector nameplate and current lens. Same-generation platforms often share the same mount, but ordering solely because the model names are similar is not worth the risk of incompatibility.

Throw Ratio by Projector Model Series

The rated throw ratio varies by series when the same VPLL-Z4107 is installed on the projector series listed below. Select the value based on the series of the actual projector.

IV. Three Checks Before Replacement

• The panel size must match. VPLL-Z4107 is designed for 4-series-inch panels. Even if the lens physically fits, projectors with a different panel size or resolution may experience image-circle and edge-illumination issues.
• Calculate the installation distance first. This lens has a rated throw ratio of 0.75-0.94:1. Use the table in Section II to calculate the distance for your venue. A fixed-focus lens offers no adjustment margin, and even a zoom lens needs 10–20 cm of extra clearance at both ends.
• Check the mount and locking mechanism. The genuine lens is calibrated to the mount used by this projector series. You must hear it lock securely into place after installation. A skewed image or soft edges are usually caused by incomplete locking rather than a defect in the lens itself.

If you are unsure, send us one photo each of the projector nameplate and the existing lens nameplate. Verification against the physical items is the safest approach.
