About This Original Lens
Ricoh 512894 Zoom #8 Lens
The 512894 Zoom #8 is a Long Throw lens manufactured by Ricoh as an OEM product. Its optical structure, lens coatings, and body tolerances are all matched to original machine standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-distance large images, wall-mounted ultra-short throw), choosing the correct throw ratio is more critical than opting for a generic lens.
This lens has a throw ratio of 1.50-3.00:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small spaces), while a larger value requires a 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.

FAQ
Q: How do I choose between an original lens and a replacement lens?
A: Original lenses are manufactured by Ricoh, with optical parameters and body tolerances calibrated to original machine standards, making them suitable 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 machine, 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: Compatibility is determined by the projector's lens mount and panel/chip size; this article lists verified compatible models. Professional projectors of the same generation and brand often share the same mount; if unsure, photograph the unit's 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. A smaller value produces a larger image (short throw/ultra-short throw suits close-range small spaces), while a larger value requires a greater installation distance. 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 512894 Zoom #8 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 used parts.
Q: What should I pay attention to when replacing the lens?
A: Before removal, ensure the projector is powered off and the cooling fan has stopped; hold the lens barrel without touching the glass, and use a blower for dust. After installation, test focus before tightening the locking screws, and clean the mount and contacts as a routine step.
Q: What is the warranty period for the lens?
A: Zorsika provides a 12-month warranty on all projector lenses; 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.
