About This Original Lens

BenQ LS1LT1 Semi Long Zoom Lens

The LS1LT1 Semi Long Zoom is a BenQ original long throw (Long Throw) lens, with optical construction, lens coating, and housing tolerances all matched to original machine standards—ready for installation with stable imaging performance. For installations with limited projection distance (such as large images from short distances, ultra-short throw against walls), choosing the correct throw ratio is more critical than selecting a universal lens.

This lens has a throw ratio of 2.22:1 - 3.67:1. Throw ratio = projection distance ÷ screen width: smaller values produce larger images (suitable for close-up small spaces), while larger values require greater installation distance. Calculate the required throw ratio range based on on-site installation distance and screen size, 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 the original unit, 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 aligned to the original machine, offering advantages in budget and lead time. Zorsika supplies both options, select according to project requirements.

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

A: Use the projector lens interface and panel/chip size as reference; this article lists validated compatible models. Engineering projectors of the same generation and brand often share interfaces. When unsure, photograph the projector nameplate and send it to Zorsika technical team 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 suitable for close-proximity small spaces), larger values require greater installation distance. Back-calculate the required throw ratio range based on installation distance and screen size, then match the focal length of this model.

Q: How does Zorsika guarantee authenticity for LS1LT1 Semi Long Zoom?

A: Zorsika provides authentic products from official factory channels, with original packaging and verifiable serial numbers; batch projects can request channel certificates to ensure no refurbished units or second-hand dismantled parts.

Q: What should I pay attention to when replacing the lens?

A: Be sure to power off and wait for the cooling fan to stop completely before disassembly; hold the lens by the barrel without touching the glass, use an air blower to gently blow away any dust; after installation, test focus first then tighten the mounting screws, and clean the mount and contacts.

Q: What is the lens warranty period?

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