Sharp L4K-20ZM – 1.98-3.34:1 Powered Zoom Lens for NP-PH2601QL/PH3501QL

Product Overview

The Sharp L4K-20ZM is a motorized long-throw powered zoom lens with a 1.98-3.34:1 throw ratio, designed for the NP-PH2601QL and NP-PH3501QL 4K large-venue laser projectors. This is the longest-throw lens in the L4K series, covering extended projection distances in large auditoriums, convention centers, and venues where the projector must be mounted at the rear of the room or in a dedicated projection booth. Powered zoom, focus, and lens shift provide complete remote optical control after installation at height.

Product Description

The L4K-20ZM is the long-throw option in the three-lens L4K series for the NP-PH2601QL and NP-PH3501QL platforms. With a 1.7x zoom ratio spanning 1.98-3.34:1, it positions the projector between approximately 14.3 and 24.0 feet from a 100-inch-wide screen at its shorter end—suitable for large convention center halls, large-venue auditoriums, and rear-of-room projection scenarios. The focal length ranges from 61.4 to 105.2mm with an f/2.5 aperture. At 19.8 lbs (8.98 kg), it is the heaviest of the three L4K lenses, reflecting the larger optical elements required for longer throw distances at 4K resolution and high brightness.

The L4K-20ZM is sold separately from the NP-PH2601QL and NP-PH3501QL projector bodies and must be specified as a distinct line item in large-venue 4K AV system designs.

Frequently Asked Questions

Q: Which projectors is the L4K-20ZM compatible with?

The L4K-20ZM is designed for the NP-PH2601QL and NP-PH3501QL 4K large-venue laser projectors and their -R variants.

Q: When should I choose the L4K-20ZM over the L4K-15ZM?

Use the L4K-20ZM when the throw ratio required exceeds 2.10:1. The L4K-15ZM (1.52-2.10:1) covers standard-to-moderate throw; the L4K-20ZM (1.98-3.34:1) is the correct choice for large venues with longer projection distances. The throw ranges overlap at approximately 1.98-2.10:1.

Q: Is this lens sold with the projector?

No. The L4K-20ZM is sold separately from the projector body and must be specified independently in AV system designs.

Q: Where can I purchase the L4K-20ZM?

Available at Creation Networks, an authorized Sharp commercial AV reseller.
