Epson Middle-Throw Zoom Projector Lens ELPLM15

A middle-throw lens is designed for medium-distance projection, meaning it sits in the sweet spot between short-throw (very close) and long-throw (very far) lenses. It gives you the flexibility to place your projector at a moderate distance from the screen while still maintaining a sharp, clear image.

No, this lens is not universal. It is compatible with specific professional Epson projector lines. You should verify your projector's model number against the compatibility list in your user manual or the Epson support site before purchasing.

The powered zoom allows you to make precise adjustments to the image size remotely, rather than manually twisting the lens barrel. This is particularly useful if the projector is mounted on a high ceiling or in a hard-to-reach location, as it lets you fine-tune the projection size from the ground.

The adjustable aperture (f/1.8 to f/2.35) gives you control over how much light passes through the lens. This is helpful for balancing brightness and contrast, especially if you are working in a room with some ambient light or if you need to match the brightness levels of multiple projectors in a single setup.

While it can be used in high-end home theaters, this lens is primarily engineered for professional installation environments like auditoriums, large conference rooms, or event spaces. Its robust build and specific throw ratio are optimized for those larger-scale, demanding projection needs.
