With this lens, users have the flexibility of installing their professional A/V systems anywhere from 15 to 290 feet from the desired projection area with minimal image quality change. With a 1.95x zoom ratio, this lens is ideally suited for larger venues such as houses of worship, auditoriums, and lecture halls.
The RS-IL04UL ultra long focus zoom lens includes independently floating elements, helping to ensure minimal image quality change and light loss throughout the zoom length of the lens, thus greatly reducing the need to over-specify projector brightness to compensate for light loss.
