WK021 Model Compatibility List (23 models total, with brightness/resolution/zoom ratio)

The following are verified compatible models for the WK021 (Panasonic projectors), with brightness, resolution, and zoom ratio listed for each:

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 body interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.

What the Zorsika Lens Offers You

Zorsika provides an OEM-spec replacement lens for the WK021, with key parameters matched item by item to the original, and supports bulk project procurement and supply.

Zorsika OEM-spec replacement model, compatible with Panasonic PT-SMZ66C, PT-SMZ67C, PT-SMZ77C, PT-SMZ57C, PT-MZ770 and 23 other models; enter WK021 in the Zorsika official website query system to find the complete model compatibility list.

• Optical matching: 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 bucks. Zorsika projector lenses are manufactured to original drawings, offering a comprehensive advantage.

Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend ordering 1 unit for testing.

What to Watch Out for When Replacing the Lens

• Power off before replacing the lens: Always shut down and wait for the cooling fan to stop before removing or installing the lens, to avoid damaging the interface with live power.
• Don't touch the glass: Fingerprints and oil will directly affect image quality. Hold the lens by the barrel, not the glass. For dust, use an air blower gently—do not wipe dry with a cloth.
• Focus before tightening: After installation, focus-test 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 practice.

FAQ

Q: My projector isn't on the list of 23 models above—can I use the WK021?

A: The list covers verified models, not all of them. Engineering projectors of the same brand and generation often share the same lens interface. It's safer to send a photo of the nameplate and original lens to Zorsika technical support for confirmation.

Q: Can the lens replace the original?

A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model numbers in the specification table above) are matched item by item to original optical parameters (focal length, throw ratio, lens group), with the same lens coating process—sharp imaging with no soft edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, and the brightness loss and color shift are visible at a glance. For engineering and exhibition scenarios, Zorsika is recommended.

Q: Why choose Zorsika instead of the original?

A: Zorsika lenses are manufactured to original optical drawings, with the lens group, coatings, and throw ratio matched item by item, and each unit resolution-tested before shipment. Compared to the original, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.

Q: What if the lens doesn't match the image size?

A: First confirm the model's lens interface and optical axis position, then choose 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: Does the WK021 come with installation instructions?

A: Yes. The lens removal and installation steps for Panasonic models like these are basically the same. Contact Zorsika sales for illustrated or video instructions for your specific model.

Q: How long is the lens warranty?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human damage (such as impact, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipment document.
