About This Genuine Lens

Christie 121-120104-01 Standard Zoom Lens

The 121-120104-01 Standard Zoom is a Christie genuine long-throw lens, with optical construction, lens coating, and chassis tolerances all matched to original specifications—ready to install with stable imaging performance. For installation environments with limited projection distance (such as large images at short throw or ultra-short throw against walls), selecting the correct throw ratio is more critical than choosing a universal lens.

This lens has a throw ratio of 1.65-2.47:1. Throw ratio = projection distance ÷ screen width: a smaller value produces a larger image (suitable for small spaces at close range), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your actual 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 Christie with optical parameters and body tolerances calibrated to the original specifications, suitable for projects with strict requirements for original manufacturer 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 lead time. Zorsika can supply both options, so choose based on project requirements.

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

A: Refer to the projector's lens mount interface and panel/chip size; this article lists verified compatible models. Engineering projectors of the same generation and brand often share mount interfaces. If unsure, take a photo of the projector 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 ratio produces a larger image (short-throw/ultra-short-throw suits close-distance small spaces), while a larger ratio requires greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match the focal length of this model.

Q: How does 121-120104-01 Standard Zoom guarantee authenticity?

A: Zorsika provides genuine factory-channel products with original packaging and verifiable serial numbers; batch projects can request channel documentation to ensure no refurbished machines or second-hand 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 before disassembly and installation; hold the lens by the barrel without touching the glass; gently blow off dust with an air blower; after proper installation, test focus first before tightening the mounting screws, and clean the mount and contacts.

Q: What is the warranty period for the lens?

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