About This Original Lens

The SL-4K-123 is an original Long Throw lens manufactured by Digital Projection. Its optical structure, lens coatings, and body tolerances are all matched to OEM 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 right throw ratio is more critical than opting for a generic lens.

This lens has a throw ratio of 1.65-2.60:1 (zoom). Throw ratio = projection distance ÷ image width: a smaller value means a larger image (ideal for close-range, small spaces), while a larger value requires a greater installation distance. Work backward from your on-site installation distance and screen size to determine the required throw ratio range, 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 Digital Projection, with optical parameters and body tolerances calibrated to OEM standards, ideal 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, 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 projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share the same mount; 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. A smaller value means a larger image (short-throw/ultra-short-throw suits close-range, small spaces), while a larger value requires a greater installation distance. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model's focal length.

Q: How can I ensure the SL-4K-123 is genuine?

A: Zorsika supplies genuine products through authorized channels, with OEM packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure they are not refurbished or second-hand 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 removing or installing; hold the lens barrel without touching the glass, use a blower for dust; after installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.
