About This Original Lens
Ricoh 512918 Long Zoom #A5 Lens
The 512918 Long Zoom #A5 is a long throw lens manufactured by Ricoh. Its optical structure, lens coatings, and body tolerances are matched to the original projector specifications, ensuring immediate installation and stable imaging. For installation environments with limited projection distance (e.g., projecting a large image from a short distance, ultra-short throw close to the wall), selecting the correct throw ratio is more critical than choosing a generic lens.
This lens has a throw ratio of 2.90-5.50:1. Throw Ratio = Projection Distance ÷ Image Width: A smaller value produces a larger image (suitable for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the on-site installation distance and screen size, then match it to this model.

Frequently Asked Questions
Q: How to choose between an original lens and an alternative lens?
A: The original lens is manufactured by Ricoh, with optical parameters and body tolerances calibrated to the original projector, making it suitable for projects with strict requirements for OEM consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount benchmarked against the original, offering advantages in budget and lead time. Zorsika can supply both options; choose based on project requirements.
Q: How can I confirm this lens will work with my projector?
A: Compatibility is determined by the projector's lens mount and panel/chip size. This article lists verified compatible models. Projectors of the same generation and brand often share mounts. If unsure, taking a photo of the projector's nameplate and sending it to Zorsika technical support for confirmation is the safest approach.
Q: How to choose the throw ratio?
A: Throw Ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short/ultra-short throw suitable for close distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the installation distance and screen size, then match it to the focal range of this model.
Q: How can I ensure the 512918 Long Zoom #A5 is authentic?
A: Zorsika supplies authentic products through official OEM channels, with original packaging and verifiable serial numbers. For bulk projects, channel credentials can be provided upon request to ensure the units are not refurbished or second-hand salvage parts.
Q: What should I pay attention to when replacing the lens?
A: Before disassembly, be sure to power off the projector and wait for the cooling fan to stop. Handle the lens by the barrel, avoiding contact with the glass elements. Use a blower to gently remove any dust. After installation, perform a focus test before tightening the mounting screws, and clean the mount and contacts while you're at it.
Q: What is the warranty period for the lens?
A: Zorsika provides a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), you can directly contact after-sales service. The warranty period is based on the date on the shipping documents.
