2. Check Lens Shift Range: Before installation, ensure the horizontal/vertical lens shift margin of the projector to avoid the image spilling over or being unable to center it.
3. Confirm Body Mount Compatibility: The Zorsika WK015 lens uses a standard Christie projector mount. Before purchasing, please confirm with the sales team that your projector model is in the compatibility list.

FAQ — Frequently Asked Questions about the Zorsika WK015

Q: What does the throw ratio of the Zorsika WK015 lens mean?

A: Throw ratio = projection distance / screen width. The smaller the ratio, the larger the image at the same distance. The Zorsika WK015 has a throw ratio of 0.46:1, 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 are compatible with the Zorsika WK015 lens?

A: The Zorsika WK015 lens is compatible with 3 Christie projector models. For details, refer to the "Compatible Projector Models" table in this article. To confirm whether a specific model is compatible, please contact Zorsika sales with a photo of the projector's nameplate, and we will verify the match between the lens and the body.

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

A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce details. The higher the value, the sharper the image. Professional projection lenses generally require MTF >50% @93lp/mm. The MTF specification for the Zorsika WK015 lens is -. In 4K projection applications, MTF is a key indicator for determining whether the lens truly supports 4K resolution.

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

A: The key difference between ultra-short-throw (0.46:1) and short-throw (typically 0.4-1.0:1) lies in installation distance: ultra-short-throw can project 100 inches at 0.3-0.5 meters, suitable for desktop interaction and replacing electronic whiteboards; short-throw requires 1-2 meters, suitable for ceiling mounting above classroom blackboards. If the room depth is less than 2 meters, ultra-short-throw is recommended; if the depth is 2-4 meters, short-throw offers better cost-effectiveness.

Q: What is the installation method for the Zorsika WK015 lens?

A: The Zorsika WK015 lens uses a standard Christie projector lens mount. Insert it into the lens bay and turn clockwise to lock it in place. The process takes about 30 seconds. For on-site installation support, contact the Zorsika sales engineer for on-site service.
