Sharp NP18ZL-4K – 1.71-2.25 Standard-Throw Zoom Lens for NP-PX1005QL
Product Overview
The Sharp NP18ZL-4K is a motorized standard-throw zoom lens with a 1.71-2.25:1 throw ratio and lens memory, designed for the NP-PX1005QL 4K UHD professional installation projector. The lens features motorized zoom, focus, and lens shift—with +50%/-30% vertical and +20%/-10% horizontal shift range—enabling precise off-axis image placement without electronic keystone correction. Lens memory stores up to three position presets for fast recall in multi-use venues.
Product Description
The NP18ZL-4K is the standard-throw lens in the NP-PX1005QL 4K-compatible lens family, covering the projection distance range most commonly required for mid-size conference rooms, classrooms, and auditoriums. At 1.71-2.25:1, the projector can be positioned approximately 12.3 to 16.2 feet from a 100-inch-wide screen. The 1.32x zoom range allows fine-tuning of image size without physical relocation. Motorized lens shift provides optical image offset that preserves the full 4K resolution without the degradation caused by digital keystone processing.
The NP18ZL-4K is sold separately from the NP-PX1005QL projector body. The bayonet-style mount allows quick lens exchange in the field.
