This lens offers convenient motorized zoom and focus capabilities, which allow for remote adjustments and simplify the setup process. It also includes lens shift and lens memory functions, making it easier to achieve perfect image alignment without physically moving the projector unit itself. The robust construction ensures durability, while its advanced optical design minimizes distortion and enhances brightness and resolution, delivering crisp, vibrant images. The NP20ZL is a high-quality accessory from NEC, designed for seamless integration and user-friendly installation without requiring special tools.
