Sharp NP21ZL-4K – 5.25-8.28 Long-Throw Zoom Lens for NP-PX1005QL
Product Overview
The Sharp NP21ZL-4K is a motorized long-throw zoom lens with a 5.25-8.28:1 throw ratio and lens memory, designed for the NP-PX1005QL 4K UHD professional installation projector. This is the longest-throw lens in the NP-PX1005QL lens family, enabling projection from extreme distances in large auditoriums, arenas, and deep rear projection booth setups. Motorized zoom, focus, and lens shift with +50%/-30% vertical and +20%/-10% horizontal range provide complete remote optical alignment after installation.
Product Description
The NP21ZL-4K extends the NP-PX1005QL lens lineup beyond the NP19ZL-4K (2.20-3.67:1), covering ultra-long projection distances from 5.25:1 to 8.28:1. At a 100-inch-wide screen, the NP21ZL-4K positions the projector approximately 37.8 to 59.6 feet away—covering the deepest auditorium configurations, stadium installations, and long-distance projection booth scenarios. The 1.58x zoom ratio allows meaningful image size adjustment without physical projector relocation.
The NP21ZL-4K is sold separately from the NP-PX1005QL projector body and features a bayonet mount for tool-free exchange.
