Sharp NP17ZL-4K – 1.24-1.78:1 Short-Throw Zoom Lens for PX1005QL

Product Overview

The Sharp NEC NP17ZL-4K is a 1.24 to 1.78:1 short-throw zoom projector lens with lens memory, engineered for NP-PX1005QL 4K UHD laser installation projectors. The bayonet-style mount allows quick lens exchange during projector installation, while motorized zoom, focus, and lens shift support precise image alignment from the projection booth or control system. For AV integrators planning a large-venue projection system with limited throw distance, this short-throw zoom lens covers screens from 40 to 500 inches.

Product Description

Fixed-lens projectors force compromises in room design; the NP17ZL-4K gives system designers the flexibility to place the PX1005QL closer to the screen than standard lenses allow, which is valuable in auditoriums, broadcast studios, and staging environments where ceiling structure or sightlines restrict projector placement. The 1.24 to 1.78:1 throw ratio, f/1.85 to f/2.5 aperture, and 18.7 to 26.5 mm focal length produce a bright, sharp 4K image across a wide range of screen sizes.

Motorized zoom and focus are controlled from the projector remote or over the network, eliminating ladder trips during commissioning. The built-in lens memory function stores zoom, focus, and shift positions, so installations that alternate between aspect ratios or screen configurations can recall presets instantly — a practical benefit for multi-purpose rooms and rental and staging workflows. Generous powered lens shift of +50%/-30% vertical and +20%/-10% horizontal lets installers align the image without physically repositioning or tilting the projector, preserving optical geometry and simplifying rigging. The bayonet mount design makes swapping between Sharp NEC 4K lens options fast and tool-free as venue requirements change. At 2.4 lb and rated for -25 to 50°C operation, the lens is suited to fixed commercial installation and touring use alike.

Frequently Asked Questions

Which projectors is the NP17ZL-4K compatible with?

The NP17ZL-4K is designed for the Sharp NEC NP-PX1005QL family of 4K UHD laser installation projectors, including the PX1005QL-B and PX1005QL-W models.

What does the lens memory function do?

Lens memory stores zoom, focus, and lens shift positions as recallable presets. Venues that switch between screen formats — for example, 16:9 presentations and wider staging looks — can return to an exact lens configuration in seconds without manual realignment.

How is the lens installed?

The bayonet-style mount allows quick, tool-free exchange on the projector. Lens installation should be performed by a qualified AV technician following the projector's installation guide, and the projector should recalibrate the lens after mounting.

Can I control zoom and focus remotely?

Yes. Zoom, focus, and lens shift are motorized and operated from the projector remote control or over the projector's network control interface, which integrates with commercial AV control systems.

What screen sizes does this lens support?

The NP17ZL-4K projects images from 40 to 500 inches diagonal, with the throw distance determined by the 1.24 to 1.78:1 throw ratio and your chosen screen width.

Does Creation Networks help with lens selection?

Yes. If you are unsure whether a short-throw, standard, or long-throw lens suits your room geometry, contact Creation Networks with your screen size and throw distance and our AV team will confirm the correct Sharp NEC lens.
