Zorsika WK133 projector lens, matched to original optical specs, compatible with C-4K650 and 1 other Wincomn projector model.


When replacing a lens on an engineering projector, the biggest fear is buying one that won't fit. This article explains once and for all which Yingkang projector models the WK133 supports and what to watch out for when selecting it.
Zorsika WK133 Projector LensCompatible Models: 1 Yingkang Projector (with brightness, resolution, and zoom ratio)
The following are verified compatible models for the WK133 (Yingkang projectors), with brightness, resolution, and zoom ratio listed for each:
| Projector Model | Brightness | Resolution | Zoom Ratio |
|---|---|---|---|
| C-4K650 | 6500 lumens | 4K (3840×2160) | 1.0-1.6:1/0.7-0.9:1 |
Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/manual for accuracy); lens compatibility is based on the chassis interface and optical structure. For models not listed, contact Zorsika technical support for confirmation.

Frequently Asked Questions
Q: What should I do if the lens doesn't match the screen size?
A: First confirm the model's lens interface and optical axis position, then select a lens with the corresponding throw ratio based on the actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.
Q: My projector isn't on the list of 1 model above — can I use the WK133?
A: The list covers verified models, but it doesn't represent all of them. Engineering projectors of the same brand and generation often share the same lens interface. To be safe, take a photo of the model nameplate and the original lens and send it to Zorsika technical support for confirmation.
Q: Can this lens replace the original one?
A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers as shown in the specification table above) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with the same lens coating process, delivering sharp imaging with no blurring at the edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in visible brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.
Q: Why choose Zorsika instead of the original manufacturer?
A: Zorsika lenses are produced according to the original optical drawings, with the lens group, coating, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared to the original manufacturer, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.
Q: How long is the lens warranty?
A: All Zorsika projector lenses come with a 12-month warranty. Under normal use, non-human-caused damage (such as impact, water damage, or unauthorized disassembly) can be handled directly through after-sales service. The warranty period is based on the date on the shipping document.
Same Specifications — Why Choose Zorsika
Zorsika provides an original-spec replacement lens for the WK133, with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.
Zorsika's same-spec replacement model is compatible with the Yingkang C-4K650 and 1 other model; enter WK133 in the Zorsika official website query system to see the complete list of compatible models.
- Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
- Resolution Testing: Each unit tested before shipment, with MTF data available
- Coating Process: Lens coatings at the same level as the original, reducing light loss
- Stable Supply: Supports bulk procurement and project supply
In short: the lens is the optical core — don't gamble on image quality to save a few dollars. Zorsika projector lenses are produced according to original drawings and offer better overall value.
Note: Actual imaging performance depends on the projector's condition and installation environment. Before bulk procurement, we recommend ordering 1 unit for testing first.
What to Watch Out for When Replacing a Lens
- Power off before replacing the lens: Before removing or installing the lens, be sure to shut down and wait for the cooling fan to stop, to avoid damaging the interface while powered on.
- Don't touch the lens elements: Fingerprints and oil will directly affect image quality. Hold the lens by the barrel, not the glass. If there's dust, use an air blower gently — don't wipe dry with a cloth.
- Focus before tightening: After installing properly, test the focus first, then tighten the fixing screws, to avoid image drift from loosening over time.
- Keep the interface clean: Dust on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer approach.
