Canon Unveils the ‘RS-IL04UL’ Lens for its REALiS Projectors

Canon U.S.A. Inc., a producer of digital imaging solutions, unveils its RS-IL04UL Ultra Long Focus Zoom Lens that can be used with Canon’s REALiS Professional A/V Series projectors.
            The RS-IL04UL lens provides users with the flexibility of installing their professional audiovisual systems anywhere from 15 feet to 290 feet from the desired projection area with minimal image quality change, Canon says.
            The RS-IL04UL lens is compatible with all current REALiS Pro A/V Series projectors, including all WUX 4000, WUX 5000, WX6000 and SX6000 models, the company says. With a 1.95X zoom ratio and a throw ratio of approximately 3.8~7.3:1, the RS-IL04UL lens is optimized for 60 feet to 600 feet screens and is suited for larger venues such as auditoriums and lecture halls.
            Similar to other lenses Canon provides for its REALiS Pro A/V Series projectors, the RS-IL04UL Ultra Long Focus Zoom Lens includes independently floating elements, that help 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, according to the company.
            For example, the brightness of the Canon REALiS WUX4000 projector drops only 17 percent from the wide angle to the telephoto setting of the standard zoom lens, while competitive products can lose up to 35 percent of their brightness in making the same adjustment, Canon says.
            “Canon is committed to providing users with a complete system to satisfy their projecting needs,” said Yuichi Ishizuka, Canon’s executive vice president and general manager of the Imaging Technologies and Communications Group. “The addition of this new lens helps expand the locations and applications where our REALiS models can be utilized,” he said.
