In the world of professional AV installation, the choice of the right lens can make or break an entire project. Whether it is a large-scale venue, a corporate event hall, or an immersive exhibition space, the ability to project a massive, razor-sharp image from a short distance is not just a convenience — it is a necessity. The Panasonic PT-BAZ822C is one of the most powerful projectors in its class, delivering 8,000 lumens of brightness with WUXGA resolution and a versatile lens shift system. However, its native throw ratio of 1.09–1.77:1 can be limiting in spaces where the projector must sit close to the screen. This is where the Zorsika WE230 lens steps in. With an ultra-short throw ratio of 0.52–0.64:1, this lens unlocks a whole new range of possibilities for the Panasonic PT-BAZ822C, and Zorsika delivers it all with the optical quality and build reliability that professionals demand.
The Panasonic PT-BAZ822C: A Powerhouse Built for Demanding Environments
The Panasonic PT-BAZ822C belongs to the acclaimed B-series laser projector lineup, engineered for venues that require exceptional brightness and image clarity. It employs a 3LCD display technology paired with a 0.64-inch chip, producing a native resolution of WUXGA (1920 × 1200) at a remarkable 8,000 lumens. This level of brightness ensures that the image remains vivid and legible even in environments with significant ambient light, making it an excellent choice for large auditoriums, conference centers, houses of worship, and rental staging applications.
The stock lens on the PT-BAZ822C offers a focal length of 15.30–24.64mm with a 1.6x zoom range and an aperture of F1.58–1.91. Its throw ratio spans from 1.09:1 to 1.77:1, which is perfectly adequate for many standard installations. The lens also supports generous shift capabilities — 44% vertical and 22% horizontal — giving installers plenty of room to position the projector off-axis while keeping the image perfectly aligned on the screen.
However, there is a scenario where the stock lens shows its limits. When a venue has a shallow depth — for example, when the back wall is only 3 to 4 meters behind the projector — the 1.09:1 minimum throw ratio restricts the maximum image size. To fill a 300-inch screen at that distance, you would need a significantly shorter throw ratio. This is precisely the gap that Zorsika has addressed with the WE230 lens.
Introducing the Zorsika WE230: Engineered for the Panasonic B-Series Platform
Zorsika is a professional supplier of projector accessories, dedicated to providing partners with high-efficiency, ultra-long-warranty, and cost-effective projector lenses, lamps, filters, and more. In the lens category, Zorsika combines deep market insight with continuous innovation to deliver solutions that meet real-world demands. Every lens in the Zorsika portfolio is designed with extremely high color fidelity, minimal light loss, 4K resolution support, and high contrast performance. The WE230 is no exception.
Designed specifically for the Panasonic B-series platform, the WE230 (product code L64-055) features a throw ratio of 0.52–0.64:1, which is dramatically shorter than the stock lens. This means that at the same projection distance, the WE230 can produce a much larger image — or conversely, the same image size can be achieved from roughly half the distance.
Let us break down the key optical specifications. The WE230 has an aperture range of F2.1 at the wide end to F2.2 at the telephoto end, with focal lengths of 7.42mm (wide) to 8.90mm (telephoto). The lens resolution is rated at 4K, which means it can fully resolve the WUXGA output of the PT-BAZ822C and has ample headroom for future 4K content. The MTF (Modulation Transfer Function) exceeds 60% at 93 line pairs per millimeter, a figure that indicates excellent sharpness and contrast retention across the entire image frame.
The lens uses a 1APS+17G glass element configuration, a combination that Zorsika has refined to deliver outstanding color accuracy and minimal chromatic aberration. The horizontal field of view is 120 degrees, while both the vertical and diagonal fields of view are 90 degrees. This wide coverage is what enables the lens to project up to 300 inches from a very short distance.
In terms of physical design, the WE230 measures φ84 × 192mm in diameter and length, with a machine protrusion of just 5.4cm. This compact form factor is a significant advantage in tight installation environments where every centimeter of space matters. The lens shift capability is ±18% vertically and ±13% horizontally. While this is less than the stock lens's 44%/22%, it is more than sufficient for most short-throw installations, where the projector is typically mounted closer to the screen centerline and less extreme shift is required.
Why 0.52–0.64:1 Changes the Game
To understand the practical impact, consider a real-world example. Suppose you need to project a 300-inch wide-screen image (approximately 6.7 meters wide) in a venue where the available throw distance is only 3.5 meters. With the Panasonic PT-BAZ822C's stock lens at 1.09:1, you would need roughly 7.3 meters of throw distance — far more than the space allows. With the Zorsika WE230 at 0.52:1, the same 300-inch image can be achieved from approximately 3.5 meters, fitting perfectly within the available space.
This short-throw capability brings several additional benefits. First, it reduces the length of HDMI and power cables, which lowers installation cost and minimizes signal degradation over long cable runs. Second, it reduces the chance of presenters or performers casting shadows across the projected image, a common frustration in lecture halls and stage settings. Third, it allows the projector to be mounted in locations that would otherwise be impossible, such as low ceilings or rear-of-house positions.
The WE230 also maintains excellent image quality at these short distances. The MTF of over 60% at 93lp/mm ensures that fine text, detailed graphics, and high-resolution video content all appear crisp and clear. The 4K-rated resolution means that even when displaying complex data visualizations or high-definition video, the lens does not become the bottleneck — the image remains sharp from edge to edge.
Zorsika: A Trusted Partner for Projector Accessories
What sets Zorsika apart in the competitive projector accessory market is not just the quality of individual products, but the company's overarching philosophy. Zorsika is committed to delivering efficient, ultra-long-warranty, and cost-effective solutions for projector lenses, lamps, and filters.

The structural design of every lens is also optimized for ease of installation, reducing labor time and minimizing the risk of errors on site.
The WE230 for the Panasonic PT-BAZ822C is a prime example of this approach. It delivers professional-grade optical performance at a fraction of the cost of the original equipment manufacturer's short-throw lens, while maintaining the build quality and warranty coverage that professionals expect. For integrators working on tight budgets or for end users looking to upgrade their existing projectors without breaking the bank, Zorsika provides a compelling alternative.
Conclusion
The Panasonic PT-BAZ822C is an outstanding projector, but its full potential is realized only when paired with the right lens. The Zorsika WE230, with its 0.52–0.64:1 ultra-short throw ratio, 4K resolution, MTF above 60%, and compact 5.4cm machine protrusion, is purpose-built to complement this machine. It solves the challenge of limited throw distance while preserving the exceptional brightness, color accuracy, and sharpness that the PT-BAZ822C is known for.
For anyone specifying or installing Panasonic B-series projectors in spaces where distance is at a premium, the Zorsika WE230 deserves serious consideration. And behind every Zorsika lens is a company that stands behind its products with professionalism, technical expertise, and a genuine commitment to customer success.
