The Christie 38-809076-61, commonly known as the "Roadie Zoom" lens, is a professional-grade, high-brightness zoom lens engineered for large-format, high-output projection systems used in major touring events, large-scale rentals, and demanding fixed installations. Featuring a versatile zoom range with a throw ratio of 2.2:1 to 3.0:1, this lens is designed for long-throw applications where the projector must be positioned a significant distance from the screen, such as in concert arenas, outdoor festivals, large houses of worship, and expansive corporate events. Its optical construction utilizes high-precision glass elements with multi-layer coatings to maximize light transmission, ensure uniform illumination, and deliver sharp, high-contrast images even when projecting at the extreme edges of its zoom and shift capabilities. This robustness makes it capable of handling the intense light output—often exceeding 30,000 lumens—from the large-venue projectors it is paired with, without introducing color fringing or focus falloff.

Built for the rigors of the road, the lens features a rugged, all-metal housing and a secure, quick-release mounting system that allows for rapid lens changes in fast-paced production environments. It incorporates manual controls for zoom, focus, and substantial lens shift, providing technicians with the precise adjustments needed to perfectly align the image onto complex screen surfaces, whether flat, curved, or angled. The generous lens shift range is particularly valuable for offsetting the projector from the ideal centerline, enabling flexible placement in trusses or projection booths where physical alignment is challenging. Despite its substantial light-gathering capability and large front element, the lens is engineered to be relatively compact and balanced for its class, facilitating safer and more straightforward rigging when the projector is flown overhead.

The Christie Roadie Zoom lens is a critical component for creating massive, impactful visuals. Its zoom range offers valuable flexibility to adjust image size without moving the projector, a crucial advantage when dealing with fixed rigging points or last-minute changes in venue layout. The optical performance is tailored to maintain fidelity with high-resolution content, supporting native 4K and beyond imaging from compatible Christie 3-chip DLP projectors. By providing a reliable, high-performance optical interface between cutting-edge projection technology and the screen, this lens empowers rental companies and system integrators to deliver consistently stunning, bright, and detailed imagery for the world's most high-profile and technically ambitious visual productions.
