About This Original Lens

Christie 121-136101-XX Short Zoom Lens

The 121-136101-XX Short Zoom is a standard throw lens manufactured by Christie as OEM, with optical structure, lens coatings, and body tolerances matched to original machine standards—ready to install and delivering stable imaging. For installations with limited projection distance (e.g., short-distance large images, wall-mounted ultra-short throw), choosing the right throw ratio is more critical than opting for a generic lens.

This lens has a throw ratio of 0.74-0.98:1. Throw ratio = projection distance ÷ image width: the smaller the value, the larger the image (ideal for short distances in compact spaces); the larger the value, the greater the installation distance required. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model.

FAQ

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

A: Original lenses are manufactured by Christie, with optical parameters and body tolerances calibrated to original machine standards, ideal for projects with strict requirements for OEM consistency; Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount benchmarked to the original, offering advantages in budget and lead time. Zorsika can supply both options—choose based on your project requirements.

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

A: Refer to the lens mount and panel/chip size on your unit; this article lists verified compatible models. Projectors of the same generation and brand often share mounts—if unsure, take a photo of the nameplate and send it to Zorsika technical support for confirmation.

Q: How do I choose the throw ratio?

A: Throw ratio = projection distance ÷ image width. The smaller the value, the larger the image (short/ultra-short throw suits compact spaces at close range); the larger the value, the greater the installation distance needed. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal range.

Q: How can I ensure the 121-136101-XX Short Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; channel documentation can be requested for bulk projects to ensure they are not refurbished or second-hand disassembled units.

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

A: Always power off the projector and wait for the cooling fan to stop before removal/installation; hold the lens barrel without touching the glass, use an air blower for dust; after installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty; for normal use and non-man-made damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly; the warranty period is based on the shipping document date.
