About This Original Manufacturer Lens

BenQ LS1ST2 Ultra Wide Zoom Lens

The LS1ST2 Ultra Wide Zoom is an original BenQ short throw lens, with optical design, lens coating, and chassis tolerances all matching original machine standards for immediate installation and stable imaging performance. For installation environments with limited projection distance (such as large images at short distances or ultra-short throw against walls), choosing the correct throw ratio is more critical than selecting a general-purpose lens.

This lens has a throw ratio of 0.75:1 - 0.93:1. Throw ratio = projection distance ÷ screen width: smaller values produce larger images (suitable for small spaces at close range), while larger values require greater installation distance. Calculate the required throw ratio range based on your actual installation distance and screen size, then match it to this model.

Note: Actual imaging performance depends on projector condition and installation environment; it's recommended to test one unit before bulk orders.

Frequently Asked Questions

Q: How do I choose between an original and a replacement lens?

A: Original lenses are manufactured by BenQ with optical parameters and machine tolerances calibrated to the original unit, suitable for projects with strict requirements for OEM consistency. Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount aligned to the original unit, offering advantages in budget and lead time. Zorsika supplies both lines—choose based on your project requirements.

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

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

Q: How do I choose the right throw ratio?

A: Throw Ratio = Projection Distance ÷ Screen Width. Smaller values produce larger images (short-throw/ultra-short-throw suitable 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 size, then match it to this model's focal length.

Q: How does LS1ST2 Ultra Wide Zoom ensure authenticity?

A: Zorsika provides genuine products from original factory channels with original packaging and traceable serial numbers; bulk project orders can request channel verification to ensure no refurbished units or second-hand removed 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 or installation. Hold the lens by the barrel without touching the glass; use an air blower for dust. After positioning, test focus before tightening the mounting screws, and clean the mount and contacts.

Q: What is the warranty period for the lens?

A: Zorsika offers a 12-month warranty on all projector lenses. Normal use with non-human damage (such as impacts, water exposure, or unauthorized disassembly) qualifies for direct after-sales service, with the warranty period based on the shipping document date.
