About This Original Lens

Vivitek GB957G Ultra Long Zoom Lens

The GB957G Ultra Long Zoom is an OEM long throw lens manufactured by Vivitek. Its optical structure, lens coatings, and body tolerances are matched to original machine standards, ensuring drop-in installation and stable imaging. For installation environments with restricted projection distance (e.g., large images from short distances, ultra-short-throw wall-mounted setups), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 4.43-8.30:1. Throw ratio = projection distance ÷ image width: a lower value produces a larger image (suitable for short distances in small spaces), while a higher value requires a longer installation distance. 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 Vivitek with optical parameters and body tolerances calibrated to the original machine, making them suitable for projects with strict OEM consistency requirements; Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original machine, offering advantages in budget and lead time. Zorsika supplies 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; verified compatible models are listed in this article. 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 select the throw ratio?

A: Throw ratio = projection distance ÷ image width. A lower value produces a larger image (short-throw/ultra-short-throw suits close-range small spaces), while a higher value requires a longer installation distance. Calculate the required throw ratio range from your installation distance and screen size, then match it to this model's focal range.

Q: How can I ensure the GB957G Ultra Long 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 the unit is not refurbished or a used pulled part.

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, and use a blower for dust; after installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.
