About This Original Lens

Christie 121-115108-XX Ultra Long Zoom Lens

The 121-115108-XX Ultra Long Zoom is a long throw lens manufactured by Christie. The optical structure, lens coating, and chassis tolerances are all matched to original machine standards, ready for immediate installation with stable imaging performance. For installation environments with limited projection distance (such as short-throw large images, ultra-short throw wall-mounted setups), selecting the right throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 4.90-8.30:1. Throw ratio = projection distance ÷ screen width: a smaller value means a larger image (suitable for short-distance, compact spaces), while a larger value requires 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 alternative lenses?

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

Q: How to confirm this lens is compatible with my machine?

A: The standard is the machine's lens interface and panel/chip size; this article lists verified compatible models. Engineering projectors of the same generation and brand often share interfaces. If uncertain, take a photo of your machine's nameplate and send it to Zorsika technical support for confirmation.

Q: How to choose the throw ratio?

A: Throw ratio = projection distance ÷ screen width. A smaller value means a larger image (short throw/ultra-short throw is suitable for compact spaces at close range), while larger values require greater installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model's focal length range.

Q: How does Zorsika ensure the 121-115108-XX Ultra Long Zoom is genuine?

A: Zorsika provides genuine products from official factory channels, with original packaging and verifiable serial numbers; bulk project orders can request channel documentation to ensure no refurbished or used disassembled 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 handling; grip the lens barrel when holding it, avoiding contact with the lens glass; use an air blower to gently blow away dust; after installation, perform focus testing before tightening the mounting screws, and clean the interface and contact points.

Q: What is the warranty period for the lens?

A: Zorsika provides 12 months warranty on all projector lenses; normal use and non-human damage (such as impacts, water damage, unauthorized disassembly) can be handled directly through after-sales service; warranty period is based on the shipping invoice date.
