The Hitachi SL-712 is a standard motorized zoom lens designed for high-end Hitachi projector models, bringing the convenience and precision of remote adjustment to professional installations. Unlike manual lenses, it incorporates small motors to control the zoom and focus functions, allowing an installer or operator to fine-tune the image size and sharpness from the projector's remote control or a central control system without needing physical access to the lens. This feature is particularly valuable in projectors mounted in difficult-to-reach locations, such as high ceilings, rear-projection rooms, or sealed enclosures, where manual adjustment would be impractical or require special equipment.

The lens provides a standard zoom range, offering the typical flexibility needed to adapt the image to the screen after the projector is permanently installed. The motorization ensures that adjustments are smooth, repeatable, and precise. Constructed with quality optics, it is engineered to match the projector's light output and resolution, maintaining image quality throughout its adjustment range. For integrators designing sophisticated control rooms, lecture halls, or digital signage networks, the Hitachi SL-712 enhances system functionality by enabling effortless calibration and making it simple to reconfigure the image for different content or screen setups, thereby adding a layer of operational flexibility to fixed installations.
