Key Points to Avoid Pitfalls in Selection and Installation

1. Confirm Throw Ratio and Installation Distance: Calculate the required throw ratio based on room depth and target screen size. The optimal installation distance for an ultra-short-throw lens is within 0.5 meters to project a 100-inch image.
2. Verify Lens Shift Range: Before installation, ensure the projector's horizontal/vertical lens shift margin is sufficient to avoid image overflow or inability to center the image.
3. Confirm Lens Mount Compatibility: The Zorsika WK17K lens uses the standard Huaying (华映) projector lens mount. Before purchasing, confirm with the sales team that your projector model is included in the compatibility list.

According to the official Zorsika maintenance manual, the Zorsika WK17K lens requires no special maintenance under normal use conditions. It will operate stably long-term as long as it is protected from severe vibration and high-temperature environments.

FAQ — Zorsika WK17K Frequently Asked Questions

Q: What does the throw ratio of the Zorsika WK17K lens mean?

A: Throw ratio = projection distance / image width. The smaller the ratio, the larger the image projected at the same distance. The Zorsika WK17K has a throw ratio of 0.48:1, making it an ultra-short-throw lens. It is recommended to calculate the achievable screen size based on the installation distance, or consult Zorsika sales for selection calculations.

Q: Which projector models is the Zorsika WK17K lens compatible with?

A: The Zorsika WK17K lens is compatible with 3 Huaying (华映) projector models. Please refer to the "Compatible Projector Models" table in this article for details. To confirm compatibility with a specific model, contact Zorsika sales and provide a photo of the projector's nameplate. We will verify whether the lens and body are compatible.

Q: What does the MTF Modulation Transfer Function represent for the lens?

A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce fine details; the higher the value, the sharper the image. Professional projector lenses generally require MTF >50% @93lp/mm. The Zorsika WK17K lens has an MTF specification of 70lp/mm center≥65%. In 4K projection applications, MTF is a key indicator to determine whether the lens truly supports 4K resolution.

Q: How to choose between an ultra-short-throw lens and a short-throw lens?

A: The core difference between ultra-short-throw (0.48:1) and short-throw (typically 0.4-1.0:1) lies in installation distance: ultra-short-throw can project 100 inches from 0.3-0.5 meters, suitable for desktop interaction or electronic whiteboard replacement; short-throw requires 1-2 meters, suitable for ceiling mounting above classroom blackboards. If room depth is less than 2 meters, ultra-short-throw is recommended; if depth is 2-4 meters, short-throw offers better cost-effectiveness.

Q: Does the Zorsika WK17K lens support 4K projection?

A: Yes. The Zorsika WK17K lens has an MTF specification of 70lp/mm center≥65%, meeting the 4K resolution standard (≥60% @93lp/mm). When used with a 4K projector, it can output a complete 4K image.

Q: What is the installation method for the Zorsika WK17K lens?

A: The Zorsika WK17K lens uses the standard lens mount for Huaying (华映) projectors. Insert it into the lens compartment and rotate clockwise to lock it in place; the entire process takes approximately 30 seconds. For on-site installation support, contact Zorsika sales engineers for on-site service.
