Sharp XP-50ZL Short Zoom Lens: Fits 8 Projector Models

Sharp Genuine Lens XP-50ZL Short Zoom is an original optical accessory for Sharp professional projectors. It is a short-throw (Short Throw) lens with a throw ratio of 0.60-0.76:1. The factory compatibility list covers 8 models. Before installation, simply verify the projector model and panel size; there is no need to make the lens fit using adapter rings. The value of a genuine lens lies not in the extra figures it adds to a specification sheet, but in the fact that it is calibrated at the factory to the optical path and lens mount of that projector series: once installed, the image circle, edge illumination, and focus 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

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

2. Throw Ratio and Installation Distance

The throw ratio is the ratio of the installation distance to the image width. This genuine lens is a zoom lens (0.60-0.76:1), so a given image size corresponds to a range of distances, and it can focus at any position within that range.

The distances above are the clear distances from the front of the lens to the screen and do not include space behind the projector for ventilation and cable connections. These figures are calculated for a 16:10 image; actual values should be confirmed through on-site measurements and the manufacturer's manual.

Image quality differs at the two ends of the zoom range: toward the short end, the image is brighter and the edges are slightly softer; toward the long end, the edges are sharper and brightness decreases slightly. Where the venue allows, the lens should ideally be positioned in the middle of the range. After installation, first find the sharpest position on the focus ring, and then fine-tune the lens shift.

3. Compatible Models (8 Projectors)

The table below is taken from the manufacturer's compatibility list. Brightness and resolution are populated from the model database; entries that cannot be retrieved are marked “—” rather than estimated.

For models not on the list, please send us photos of the projector nameplate and current lens for compatibility verification. Same-generation platforms often share the same mount, but the risks of ordering solely because the model numbers are similar are not worth taking.

Throw Ratio by Model Series

The nominal throw ratio varies by series when the same XP-50ZL Short Zoom is installed on the models below, so select the value for the series of the actual projector.

4. Three Checks Before Replacement

• Confirm the projector chip and resolution. Genuine lenses are designed for a specific panel size. If the panel specifications differ, the image circle cannot cover the full image, resulting in vignetting or light loss at the edges after installation.
• Calculate the installation distance first. This lens has a rated throw ratio of 0.60-0.76:1. Use the table in Section 2 to calculate the distance for your venue. Fixed-focus lenses offer no adjustment range, while zoom lenses should also allow a 10–20 cm margin at both ends of the range.
• Verify the mount and locking mechanism. Genuine lenses are calibrated to the mounts of the corresponding projector series. After installation, you must hear the lock engage fully. 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 each of the projector nameplate and the nameplate on the existing lens and send them to us. Verification against the actual hardware is the safest approach.
