One of the standout offerings from Zorsika is the WJ124 (Electric) projector lens, a powerful solution specifically engineered to serve as a compatible alternative for the Christie DWU1100-GS. Let us take a deep dive into how these two products work together and why this combination deserves serious consideration from professionals in the field.
Understanding the Christie DWU1100-GS
The Christie DWU1100-GS is a 1DLP projector built around a 0.67-inch chip, delivering WUXGA resolution at 1920x1200 pixels. With a brightness level of 11,000 lumens, this machine is clearly designed for large venues where ambient light cannot be fully controlled. Think of concert halls, auditoriums, houses of worship, corporate event spaces, and large-format simulation environments.
The native lens that comes with the DWU1100-GS features a throw ratio range of 1.22 to 1.52:1, an aperture range of F 2.0 to 2.32, and a focal length spanning 18.07mm to 22.59mm. The zoom ratio is 1.25X, which provides a modest but functional range of adjustment. Lens shift capabilities are quite generous, with vertical shift of plus or minus 40 percent and horizontal shift of plus or minus 30 percent. These specifications make the DWU1100-GS a flexible machine for a wide variety of installation scenarios.
However, in many real-world applications, the native lens may not provide the ideal throw ratio or shift range that a specific venue demands. This is where a high-quality compatible lens like the Zorsika WJ124 (Electric) becomes incredibly valuable.
Introducing the Zorsika WJ124 (Electric) Projector Lens
The Zorsika WJ124 (Electric) carries the product code D67-072 and is built on the A06 high-brightness platform, which also supports the A02 and A06 platforms. This means it is designed to handle the demanding optical requirements of high-lumen projectors like the Christie DWU1100-GS without any compromise in performance.
The lens features an aperture range of F 2.2 to 2.4, with a focal length of 9.37mm at the wide end and 12.11mm at the telephoto end. What makes this lens particularly noteworthy is its throw ratio of 0.62 to 0.8:1. This is significantly shorter than the native 1.22 to 1.52:1 throw ratio of the DWU1100-GS, which opens up entirely new installation possibilities. With the WJ124, installers can place the projector much closer to the screen while still achieving a massive image size, making it ideal for venues with limited ceiling height or restricted mounting positions.
The resolution capability of the WJ124 is listed as WUXGA and 4K, meaning it can fully resolve the native WUXGA output of the DWU1100-GS while also being future-proof for higher-resolution content. The lens resolution is rated at 4K, ensuring that every pixel of detail is rendered with clarity and precision. The projectable image size can reach up to 500 inches, with a recommended performance range of up to 300 inches for optimal sharpness and brightness distribution.
One of the most impressive specifications of the Zorsika WJ124 is its MTF value, which exceeds 60 percent at 66 line pairs per millimeter across any field position. This is a strong indicator of the lens's ability to maintain sharpness and contrast from the center of the image all the way to the edges. For professionals who demand consistent image quality across the entire screen, this is a critical metric, and Zorsika delivers on it convincingly.
The physical dimensions of the lens are 144mm in diameter and 239.77mm in length, which is a compact and manageable size for a lens of this caliber. The panel compatibility is 0.67 inch, matching the DWU1100-GS perfectly. In terms of lens shift, the WJ124 offers a vertical shift range of plus or minus 53 percent and a horizontal shift range of plus or minus 23 percent. Compared to the native lens's vertical shift of plus or minus 40 percent, the WJ124 actually provides even greater vertical adjustment flexibility, which is a significant advantage in installations where the projector cannot be mounted directly in line with the center of the screen.
Perhaps the most compelling number in the entire specification sheet is the light efficiency rating. The Zorsika WJ124 achieves 95.6 percent light efficiency compared to the original lens. This means that when you swap the native lens for the WJ124, you lose less than 5 percent of the available light output. For a projector that already pushes 11,000 lumens, preserving that brightness is essential, and Zorsika has engineered the WJ124 to ensure that virtually all of that light reaches the screen.
Why Zorsika WJ124 (Electric) Is the Smart Choice for Christie DWU1100-GS Users
There are several compelling reasons why professionals should consider the Zorsika WJ124 (Electric) as their go-to lens for the Christie DWU1100-GS.
First, the throw ratio advantage cannot be overstated. The native lens requires a throw ratio of 1.22 to 1.52:1, which means for a 300-inch image, the projector needs to be placed roughly 8 to 10 meters away from the screen. The WJ124, with its 0.62 to 0.8:1 throw ratio, can achieve the same 300-inch image from just 4 to 5.5 meters away. This dramatically reduces the physical space required for installation and opens up venues that would otherwise be incompatible with the DWU1100-GS due to space constraints.
Second, the electric lens operation makes the WJ124 exceptionally convenient for live events and rental applications. With motorized zoom, focus, and shift controls, operators can make adjustments remotely via control systems such as Crestron, AMX, or Christie's own TCI. This level of automation saves time during setup and allows for seamless adjustments during a show without anyone needing to physically touch the lens.
Third, the optical performance is outstanding. With 4K resolution support, MTF above 60 percent at 66lp/mm across all fields, and 95.6 percent light efficiency, the WJ124 does not sacrifice image quality for the benefits of a shorter throw ratio and greater shift range. Zorsika has clearly invested heavily in the optical design to ensure that this lens performs at a level that meets or exceeds the expectations of professional users.
Fourth, the build quality and structural design from Zorsika ensure that installation is straightforward. The lens is designed with clear alignment markers and a robust mounting interface that makes the swap-out process quick and hassle-free. For rental companies that turn over equipment frequently, this ease of installation translates directly into time and cost savings.
The Zorsika Commitment to Partners
