About This Original Lens

BenQ LS1ST1 Wide Zoom Lens

LS1ST1 Wide Zoom is a BenQ genuine Standard Throw lens; its optical construction, lens coatings, and chassis tolerances are all matched to original specifications, ensuring plug-and-play installation with stable imaging performance. For installations with limited throw distance (e.g., short-throw large image, ultra-short-throw wall-mounted), selecting the correct throw ratio is more critical than choosing a universal lens.

The throw ratio for this lens is 1.25:1 - 1.79:1. Throw ratio = throw distance ÷ image width: smaller values produce larger images (suitable for small spaces with close range), while larger values require greater installation distance. Calculate the required throw ratio range based on your on-site installation distance and screen dimensions, then match it to this model.

Frequently Asked Questions

Q: How to choose between original and alternative lenses?

A: Original lenses are manufactured by BenQ, with optical parameters and machine tolerances calibrated to OEM specifications, suitable for projects with strict requirements for original factory consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount interface matching the original machine, offering advantages in budget and delivery time. Zorsika can supply both options—select based on your project requirements.

Q: How do I confirm this lens works with my machine?

A: Use the projector lens interface and panel/chip size as reference; this article lists verified compatible models. Projectors of the same generation and brand often share common interfaces. If unsure, photograph the machine nameplate and send it to Zorsika technical support for confirmation.

Q: How to choose the Throw Ratio?

A: Throw Ratio = Projection Distance ÷ Screen Width. Smaller values produce larger images (short-throw/ultra-short-throw suits small spaces with close proximity), while larger values require greater installation distances. Back-calculate the required throw ratio range based on your installation distance and screen size, then select the corresponding focal length for this model.

Q: How does Zorsika guarantee the LS1ST1 Wide Zoom is genuine?

A: Zorsika supplies factory-authorized genuine products with original packaging and verifiable serial numbers. Bulk projects can request channel documentation to ensure no refurbished or second-hand disassembled parts.

Q: What should I watch out for when replacing the lens?

A: Always power off and wait for the cooling fan to stop before removal and installation. Hold the lens by the barrel, not the glass. Use an air blower to gently remove dust. After installation, test focus before tightening the mounting screws, and clean the mount interface and contacts.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with 12-month warranty. Normal use and non-human damage (such as impacts, liquid exposure, unauthorized disassembly) can be handled directly through after-sales service. Warranty period is calculated from the invoice date.
