The lens delivers a combination of brightness and clarity that enhances every projection. Its wide aperture range allows for:

• High Brightness Output: Maintaining vivid image quality even in well‑lit rooms.
• Low Distortion: Straight edges and accurate geometry across the entire field of view.
• Consistent Color Fidelity: Minimal chromatic aberration ensures true-to-source color reproduction.

Zoom Flexibility

The 0.978‑1.32:1 zoom ratio provides a practical balance between wide‑angle coverage and moderate telephoto reach, enabling users to adapt the lens for various screen sizes without sacrificing image integrity.

Installation and Maintenance Tips

• Alignment: Use the integrated alignment marks on the lens housing to ensure precise positioning relative to the projector’s optical axis.
• Cleaning: Apply a microfiber cloth with a mild, non‑abrasive cleaner. Avoid direct contact with the glass surfaces.
• Storage: When not in use, store the lens in its protective case to prevent dust accumulation and physical damage.
