Sharp NP20ZL-4K – 3.54-5.36:1 Long-Throw Zoom Lens for PX1005QL

Product Overview

The Sharp NEC NP20ZL-4K is a 3.54 to 5.36:1 long-throw zoom projector lens with lens memory, designed for NP-PX1005QL 4K UHD laser installation projectors. It allows the projector to be mounted at the rear of large venues — auditoriums, houses of worship, and broadcast studios — while still filling screens up to 500 inches. Motorized zoom, focus, and generous lens shift make this long-throw projector lens straightforward to align and commission in fixed commercial AV installations.

Product Description

Large venues often require the projector to live in a projection booth or rear rigging position far from the screen, and the NP20ZL-4K covers exactly that geometry. Its 3.54 to 5.36:1 throw ratio places the PX1005QL three and a half to more than five screen-widths back, while the f/1.85 to f/2.41 aperture and 52.8 to 79.1 mm focal length preserve brightness and sharpness across the zoom range. The result is a clean 4K image on screens from 40 to 500 inches without compromising projector placement.

The bayonet-style mount enables quick, tool-free lens exchange, so integrators and rental and staging operators can adapt one PX1005QL projector platform to different venues by swapping optics. Motorized zoom and focus are operated from the projector remote or network control interface, removing the need for lift access during fine alignment. The lens memory function stores zoom, focus, and shift positions as recallable presets — valuable in multi-purpose venues that alternate between screen formats or staging configurations. Powered lens shift of +50%/-30% vertical and +20%/-10% horizontal aligns the image to the screen without tilting the projector, maintaining optical geometry and avoiding resolution-degrading keystone correction. For projection system designs that need a shorter throw on the same projector, see the companion Sharp NEC NP17ZL-4K short-throw zoom lens.

Technical Specifications

Frequently Asked Questions

Which projectors does the NP20ZL-4K fit?

The NP20ZL-4K is built for the Sharp NEC NP-PX1005QL family of 4K UHD laser installation projectors, including the PX1005QL-B and PX1005QL-W models.

How far from the screen can the projector be mounted with this lens?

The 3.54 to 5.36:1 throw ratio means the projector can sit roughly 3.5 to 5.4 times the screen width away. For a 16-foot-wide screen, that allows mounting between about 57 and 86 feet back — ideal for projection booths and rear truss positions.

Does the lens support motorized control?

Yes. Zoom, focus, and lens shift are motorized and controlled from the projector remote or its network interface, which can be tied into a commercial AV control system.

What is the benefit of lens memory in a long-throw installation?

Lens memory recalls stored zoom, focus, and shift positions instantly, so venues that switch between presentation formats or staging looks can return to a calibrated setup without manual realignment at height.

How difficult is lens installation?

The bayonet mount allows quick, tool-free exchange. We recommend a qualified AV technician handle installation on rigged projectors and run lens calibration after mounting.

What if my room needs a shorter throw distance?

The PX1005QL lens family includes shorter options such as the NP17ZL-4K short-throw zoom. Contact Creation Networks with your screen width and mounting distance and we will confirm the correct lens for your installation.
