The Sony VPLL-FM22 is a fixed short-focus zoom lens designed as an accessory for specific models within Sony's professional VPL-F series of high-brightness installation projectors. This lens is engineered for applications where the projector must be positioned very close to the screen but still produce a large image, such as in tight boardrooms, small classrooms, retail displays, or rear-projection cabinets where space is severely limited. The "short-focus" characteristic allows for greater installation flexibility in constrained environments, enabling large-screen presentations from a projector mounted just a few feet from the wall or screen. While it is a zoom lens, its range is typically limited compared to standard lenses, providing a moderate amount of adjustment to fine-tune the image size without moving the projector, which is crucial for achieving a perfect fit during installation.

Constructed with high-precision optical glass and advanced coatings, the lens is designed to maintain the native image quality and light output of the host VPL-F projector, delivering sharp focus, high contrast, and accurate color reproduction. As a fixed lens (non-interchangeable in the field for this specific model designation), it is often selected at the time of projector purchase or ordered as a specific variant of the projector model to match the venue's throw requirements. It integrates seamlessly with the projector's motorized lens control system, allowing for remote adjustment of zoom and focus via the projector's menu or external control systems, facilitating precise calibration during setup.

For system designers and integrators, selecting the correct short-focus lens like the VPLL-FM22 is a critical step in ensuring a successful installation where throw distance is a primary constraint. It allows the powerful, high-lumen output of Sony's installation projectors to be utilized effectively in spaces that cannot accommodate a projector at a standard distance. By providing a dedicated optical solution for short-throw applications, this lens ensures that venues with spatial limitations can still benefit from large-format, bright, and high-quality projected imagery, making it an essential component for tailored professional visual systems.
