Epson CB - L720U: A High - End Projection Solution
The Epson CB - L720U is a well - known projector in the market, renowned for its advanced features. It employs the 3LCD display technology, which ensures vivid and natural color reproduction. With a chip size of 0.64 inches and a WUXGA resolution of 1920 x 1200, it can deliver sharp and detailed images. The projector boasts a high brightness of 7000 lumens, making it suitable for use in various lighting conditions, from well - lit conference rooms to large auditoriums.
Its throw ratio ranges from 1.35 - 2.2:1, and the F - number is between 1.5 - 1.7. The lens has a focal length of 20.0mm - 31.8mm and a zoom ratio of 1.6. Additionally, it offers significant lens shift capabilities, with a vertical shift of - 20% to + 20% (centered vertically) and a horizontal shift of - 50% to + 50% (centered horizontally). These features provide flexibility in projector placement, allowing users to achieve the desired image position without having to precisely position the projector itself.
Zorsika WK051: A Feature - Packed Alternative
Zorsika's WK051 projector lens, with the product code D67 - 047, is a high - performance alternative that can enhance the capabilities of the Epson CB - L720U. It has an Ff of 2.0 / 6.9mm and is designed to support 4K resolution, ensuring that users can enjoy the latest in high - definition content. The lens uses a 1P + 16G optical design, which contributes to its excellent image quality.
One of the most impressive features of the WK051 is its large projection range. It can project an image up to 500 inches, with a performance range of 300 inches. This makes it ideal for large - scale presentations, movie screenings, and other applications where a large image is required. The MTF (Modulation Transfer Function) value of 70lp/mm center≥65% indicates that the lens can maintain high image sharpness and contrast, even at the center of the projected image.
The lens is designed for the L530 platform model and has a compact size of φ112mm * 169mm, making it easy to install and handle. With a panel size of 0.67 inches and a resolution of 4K/2K, it can fully utilize the high - resolution capabilities of modern projectors. The throw ratio of 0.46:1 is significantly lower than that of the original Epson lens, which means that the WK051 can project a large image from a much shorter distance. This is a great advantage in space - constrained environments, such as small meeting rooms or classrooms.
Lens Shift and Optical Efficiency
The Zorsika WK051 also offers impressive lens shift capabilities. It has an upward and downward displacement of 85.2% and a left - to - right displacement of 39.6%. These values are much higher than those of many standard lenses, providing users with greater flexibility in adjusting the image position. Whether the projector needs to be placed off - center or at an angle, the WK051 can easily compensate for these misalignments, ensuring a perfectly rectangular and centered image.
In terms of optical efficiency, the WK051 achieves an impressive 86.5% compared to the standard lens. This means that it can transmit more light from the projector to the screen, resulting in brighter and more vivid images. Even in well - lit environments, the projected image remains clear and visible, reducing the need for additional lighting control measures.
Compatibility and Cost - Effectiveness
Zorsika is well - known for its ability to produce high - quality alternative lenses for many well - known projector brands, and the WK051 is no exception. It is designed to be fully compatible with the Epson CB - L720U, allowing users to upgrade their projector's performance without having to purchase a completely new projector. This not only saves money but also reduces electronic waste, making it an environmentally friendly choice.
Moreover, Zorsika offers a long - warranty period for its products, providing customers with peace of mind. The company is committed to providing efficient and reliable service, ensuring that any issues with the lens are resolved promptly. With its combination of high - performance features, excellent compatibility, and cost - effectiveness, the Zorsika WK051 projector lens is an excellent choice for those looking to enhance the capabilities of their Epson CB - L720U projector.
