Sony VPLL-4008 Standard Throw Lens Guide for VPL-F725HZL VPL-F720HZL VPL-F1306ZL VPL-F1006ZL

Sony Genuine Lens VPLL-4008 is an OEM optical accessory for Sony engineering projectors. It is a standard-throw (Standard Throw) lens with a 1.0:1 throw ratio, designed for 4-series-inch panels. The manufacturer’s compatibility list covers 4 models; before installation, simply verify the projector model and panel size, with no need to force a fit using adapter rings. The value of a genuine lens lies not in the extra figures in the specification sheet, 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 focusing travel are all set to their design values, so there is no need to use keystone correction to compensate for image quality.

1. Lens Specifications

These specifications are subject to the official manufacturer specifications. For mechanical dimensions, flange distance, and mount type not shown in the specification table, please contact us with the projector model for verification. Placing an order solely because the model numbers are similar carries the risk that the lens will not fit.

2. Calculating Installation Distance from the Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This genuine lens has a fixed focal length (1.0:1), so the installation distance varies linearly with the image size, with no room for adjustment. Accurate measurements are essential before installation.

These figures represent the clear distance from the front of the lens to the screen and do not include space for rear projector ventilation or cable connections. The values are calculated for a 16:10 image; actual dimensions should be verified on site and are subject to the official manufacturer manual.

3. Compatible Models (4 units)

The following table is taken from the manufacturer’s compatibility list. Brightness and resolution are populated from the model database; where the data is unavailable, “—” is shown, and no values are inferred.

To check whether a model outside the list is compatible, send us photos of the projector nameplate and the existing lens nameplate. Platforms of the same generation often share the same mount, but ordering based solely on a similar model number is not worth the risk.

Throw Ratios by Projector Series

The nominal throw ratio differs when the same VPLL-4008 is used with the series listed below, so select the value based on the series of the projector you actually have.

4. Three Checks Before Replacement

• Make sure the panel size matches. VPLL-4008 is designed for 4-series-inch panels. Even if the lens fits the mount, projectors with different panel sizes or resolutions may experience problems with the image circle and edge illumination.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.0:1. Use the table in Section 2 to match the dimensions of your installation site. A fixed-focus lens offers no adjustment margin, while zoom lenses should also allow 10–20 cm at both ends.
• Check the mount and locking mechanism. The genuine 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, take one photo of the projector nameplate and one of the existing lens nameplate and send them to us. Verification against the actual equipment is the most reliable approach.
