High - Resolution and Excellent Optical Performance
The WK051 lens has a resolution of 4K, ensuring that it can fully utilize the high - resolution capabilities of the Epson CB - L690E. With a lens resolving power of 4K and a jingpian_type of 1P + 16G, it delivers clear and sharp images with minimal distortion.

For example, it can project a large 500 - inch image within a relatively short throw distance, which is a great space - saving solution. The performance range of 300 inches also provides flexibility in choosing the appropriate image size for different applications.
Enhanced Lens Shift Functionality
The lens offers impressive lens shift capabilities, with an 85.2% vertical displacement and a 39.6% horizontal displacement. This means that users can easily adjust the position of the projected image without having to physically move the projector. Whether it's to correct for off - center installation or to fit the projection within a specific area, the Zorsika WK051 provides the necessary flexibility.
High Light Efficiency
Compared to the standard lens, the Zorsika WK051 has a light efficiency of 86.5%. This means that it can effectively transmit more of the projector's light output, resulting in brighter and more vivid images. In combination with the high - brightness Epson CB - L690E, this lens can create an immersive viewing experience even in well - lit environments.
Scientific Structural Design for Easy Installation
