Sharp NP19ZL – 2.22-3.67:1 Medium-Throw Zoom Lens for PX Series

Product Overview

The Sharp NEC NP19ZL is a 2.22 to 3.67:1 medium-throw zoom projector lens with lens shift and lens memory, one of six optional lenses for NEC PX Series installation projectors. It is built for projection installations where the projector sits at a moderate distance from the screen — typical of conference rooms, halls, auditoriums, and exhibition spaces. The user-installable bayonet design lets AV integrators match the lens to the room without special tools, simplifying large-venue projector deployment.

Product Description

Choosing the correct throw ratio is the foundation of a successful fixed projection installation, and the NP19ZL covers the medium-throw range that suits most mid-sized commercial venues. With a 2.22 to 3.67:1 throw ratio, a fast f/1.86 to f/2.48 aperture, and a 32.9 to 54.2 mm focal length, the lens delivers a bright, evenly focused image when the projector is mounted toward the middle or rear of the room — a common requirement in lecture halls, hotel ballrooms, and corporate all-hands rooms where ceiling positions are fixed.

The NP19ZL is compatible with the NEC NP-PX700W/PX750U/PX800X, NP-PX700W2/PX750U2/PX800X2, NP-PX803UL-BK/PX803UL-WH, and NP-PX1004UL-BK/PX1004UL-WH installation projectors. Lens shift allows the projected image to be aligned to the screen without tilting the projector, preserving image geometry and avoiding keystone correction that degrades resolution. The lens memory function stores position presets, useful in multi-purpose rooms that alternate between screen formats. Because the lens installs without special tools, integrators can stock a single PX Series projector platform and swap optics as project requirements change — an efficient approach for rental and staging inventories and phased commercial AV deployments. Pair the NP19ZL with the rest of the Sharp NEC optional lens family, from short-throw to long-throw, to cover virtually any room geometry with one projector line.

Frequently Asked Questions

Which projectors accept the NP19ZL lens?

The NP19ZL fits NEC PX Series installation projectors: NP-PX700W, PX750U, PX800X, their second-generation PX700W2/PX750U2/PX800X2 versions, the PX803UL laser models, and the PX1004UL laser models.

Is the NP19ZL the right throw ratio for my room?

The 2.22 to 3.67:1 ratio means the projector sits roughly 2.2 to 3.7 times the screen width away from the screen. Measure your screen width and available mounting distance; if the projector must sit closer, consider a short-throw lens, and if farther, a long-throw option such as the NP21ZL.

Can I install the lens myself?

Yes. The NP19ZL is designed for end-user installation and requires no special tools. After mounting, run the projector's lens calibration before final alignment.

Does the lens support lens shift?

Yes. Lens shift moves the image vertically and horizontally on the screen without tilting the projector, preserving optical geometry and avoiding resolution loss from digital keystone correction.

What is the lens memory function used for?

Lens memory stores zoom, focus, and shift positions as presets. Venues that alternate between different screen sizes or aspect ratios can recall an exact lens configuration instantly.

Can Creation Networks help me verify lens compatibility?

Yes. Send us your projector model, screen size, and throw distance and our commercial AV team will confirm whether the NP19ZL or another Sharp NEC lens fits your installation.
