About This Original Lens

BenQ LS1ST4 Ultra Short Fixed Lens

The LS1ST4 Ultra Short Fixed is a factory-original ultra short throw lens from BenQ, with optical construction, lens coatings, and housing tolerances all matched to original machine standards—ready for installation with stable imaging performance. For installation environments with limited projection distance (such as short-throw large images, wall-mounted ultra short throw), choosing the correct throw ratio is more critical than selecting a general-purpose lens.

This lens has a throw ratio of 0.38:1. Throw Ratio = Projection Distance ÷ Screen Width: a smaller value produces a larger image (suitable for close-proximity small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your on-site installation distance and screen size, then match it to this model.

Frequently Asked Questions

Q: How to choose between original and replacement lenses?

A: Original lenses are manufactured by BenQ with optical parameters and machine tolerances calibrated to the original specifications, suitable for projects with strict OEM consistency requirements. Zorsika replacement lenses are independently designed and manufactured to equivalent specifications, with throw ratio, imaging circle, and mount interface matching the original machine. Zorsika supplies both options—select based on your project requirements.

Q: How to confirm this lens works with my machine?

A: Refer to the machine's lens interface and panel/chip dimensions; the verified compatible models are listed above. Same-generation, same-brand engineering projectors often share common interfaces. When unsure, photograph the machine nameplate and send it to Zorsika technical support for confirmation.

Q: How to choose the right throw ratio?

A: Throw ratio = projection distance ÷ screen width. Smaller values produce larger images (short-throw/ultra-short-throw ideal for close-proximity small spaces), while larger values require greater installation distances. Calculate the required throw ratio range based on your installation distance and screen dimensions, then match it to this model's focal length range.

Q: How does Zorsika guarantee authenticity for LS1ST4 Ultra Short Fixed?

A: Zorsika provides genuine original channel products with original factory packaging and traceable serial numbers; bulk projects can request channel verification to ensure no refurbished or used dismantled parts.

Q: What to watch for when installing a replacement lens?

A: Always power off and wait for the cooling fan to stop before handling; grip the lens barrel and avoid touching the glass elements; use an air blower to gently remove dust. After proper installation, test focus before tightening the mounting screws, and clean the interface and contacts.

Q: What is the warranty period for lenses?

A: All Zorsika projector lenses come with a 12-month warranty; normal use and non-human damage (such as impacts, water ingress, or unauthorized disassembly) can be handled directly through after-sales service. Warranty period is based on the shipping invoice date.
