The Konica Minolta 2.2-3.0:1 zoom lens is a high-performance optical component engineered specifically for large-venue, high-brightness digital cinema and professional projection applications, notably compatible with the Christie HD+35K series of projectors. This lens is designed to address the demanding requirements of fixed installations in auditoriums, large corporate venues, houses of worship, and command and control centers where throw distances and screen sizes vary significantly. Its core feature is a versatile zoom ratio that provides installation flexibility, allowing projectionists and system integrators to adjust the projected image size without physically moving the projector, which is crucial for fine-tuning alignment and filling specialized screen formats. The optical formula is optimized to resolve the high native resolution of 4K or 2K content from the matched projector, ensuring edge-to-edge sharpness and minimal distortion across the entire field of view.

Constructed from precision-ground glass elements with advanced multi-coatings, the lens is built to transmit the immense light output of a 35,000-lumen-class projector with exceptional fidelity and efficiency. The coatings are critical for maximizing light throughput, minimizing internal reflections and flare, and ensuring consistent colorimetry, which is paramount for maintaining accurate color reproduction in digital cinema and simulation environments. The lens assembly incorporates robust, manual controls for focus, zoom, and lens shift, which are typically large, dampened, and engineered for smooth, precise adjustments during the calibration phase of installation. The barrel is constructed from durable metals to maintain optical alignment over time, even when subjected to thermal cycling from the projector's powerful lamp and cooling system.

This lens represents a strategic investment in image quality and installation versatility. It enables the Christie projector to be positioned at a throw distance approximately 2.2 to 3.0 times the screen width, a range that accommodates many standard large-venue architectural constraints. Proper integration requires meticulous alignment and calibration to achieve the performance benchmarks for sharpness and uniformity that such high-end systems demand. As a matched accessory from a premier optical manufacturer, it ensures that the projector's potential for brightness, contrast, and resolution is fully realized, delivering a immersive, detailed, and visually stable experience for large audiences.
