Why Zorsika WB017 Remains a Lens of Sustained Interest for Buyers
The Zorsika WB017 is compatible with mainstream Eiki projector models. The most common issues buyers face during selection are: high original OEM lens prices, unstable supply lead times, and inconsistent quality of third-party lenses with substandard MTF/resolution. Zorsika addresses these pain points by offering drop-in replacement lens solutions with the same specifications as the original, all of which have passed optical tests and are covered by a free replacement warranty for non-human damage during the warranty period.
Key Points to Avoid Mistakes in Selection and Installation
- Confirm the throw ratio and installation distance — Calculate the required throw ratio based on the room depth and target screen size. For ultra-short throw lenses, the optimal installation distance is 1-2 meters for a 100-inch image;
- Verify the lens shift range — Before installation, ensure that the horizontal/vertical shift margin of the projector position is sufficient to avoid image overflow or inability to center the image;
- Confirm lens mount compatibility — The Zorsika WB017 lens uses the standard Eiki projector lens mount. Before purchase, please confirm with our sales team that your projector model is on the compatibility list.

FAQ — Zorsika WB017 Common Questions
Q: What does the throw ratio of the Zorsika WB017 lens mean?
A: The throw ratio = projection distance / image width. The smaller the ratio, the larger the image can be projected from the same distance. We recommend calculating the achievable screen size based on your installation distance, or consulting Zorsika sales for selection calculations.
Q: Which projector models are compatible with the Zorsika WB017 lens?
A: The Zorsika WB017 lens is compatible with 2 Eiki projector models. Please refer to the "Compatible Projector Models" table in this article for details. To confirm compatibility with a specific model, please contact Zorsika sales with a photo of the projector's nameplate, and we will verify the lens-to-projector match.
Q: What does the MTF (Modulation Transfer Function) of the lens represent?
A: MTF (Modulation Transfer Function) indicates the lens's ability to reproduce fine details; higher values produce sharper images. Professional projector lenses generally require MTF > 50% @93lp/mm. The Zorsika WB017 lens has an MTF of > 60% @93lp/mm. In 4K projection applications, MTF is a key indicator of whether the lens truly supports 4K resolution.
Q: Does the lens require re-calibration after installation?
A: No — the mount is identical to the original. After installation, simply fine-tune the focus and zoom based on actual projection distance. If image anomalies (black borders, light leakage, or out-of-focus) occur, first check that the lens is fully seated in the mount, then verify that the projector firmware version is compatible with the lens.
Q: Does the Zorsika WB017 lens support 4K projection?
A: Yes. The Zorsika WB017 lens has an MTF of > 60% @93lp/mm, meeting the 4K resolution standard (≥ 60% @93lp/mm). When paired with a 4K projector, it can deliver a full 4K image.
Q: What is the installation method for the Zorsika WB017 lens?
A: The Zorsika WB017 lens uses the standard Eiki projector lens mount. Insert it into the lens compartment and rotate clockwise to lock — the process takes about 30 seconds. For on-site installation support, please contact Zorsika sales for an engineer visit.
