The Christie 104-115101-01 is an ultra-high-ratio zoom lens engineered for large-venue projectors where extreme placement flexibility is the primary requirement. With a massive 4.5-7.5:1 zoom range for SXGA+ models (and 4.1-6.9:1 for HD models), this lens offers one of the widest adjustments available, allowing the image size to be varied enormously without moving the projector. This capability is critical for multi-purpose venues like large auditoriums or houses of worship where a single projector might need to serve different screen configurations, or for rental companies that require a single lens to work in a wide variety of room sizes. It provides system integrators with the ultimate tool to overcome challenging or variable throw distances, enabling precise image sizing from a vast spectrum of possible projector positions.

Designed for high-brightness Christie projectors with 0.95-inch DLP imagers, this lens incorporates complex optics to maintain acceptable image quality across its extraordinary zoom range. However, the trade-off for such immense flexibility is typically a smaller maximum aperture (higher f-number), which reduces the total light transmission compared to lenses with a smaller zoom ratio. This means some of the projector's raw brightness is sacrificed to gain placement versatility. The lens is built into a substantial, durable metal barrel with manual zoom and focus controls for precise calibration during installation. For the most demanding and variable installation scenarios, the Christie 104-115101-01 is the specialized solution that provides unparalleled freedom in projector placement, making it possible to achieve a correctly sized image where few other lenses could.
