Canon U.S.A., Inc., has launched two new portable 4K UHD broadcast lenses for use with broadcast cameras featuring 2/3-inch sensors: the Canon CJ45ex9.7B 4K UHD portable zoom lens reportedly provides users with the highest zoom ratio in its class, and the Canon CJ45ex13.6B 4K UHD portable zoom lens features both the highest zoom ratio and longest focal length in its class, the company claims.
The Canon CJ45ex9.7B and CJ45ex13.6B lenses both feature a broad 45x zoom ratio and wide-angle focal length of 9.7 mm to 437 mm and 13.6 mm to 612 mm, respectively. Both telephoto zoom lenses are ideal pieces of equipment for Electronic Field Production (EFP) broadcast applications including wildlife/nature, sports, live events, documentaries, and helicopter/aerial. Additionally, both lenses are well suited for mid-size broadcast vans and surveillance applications.
“As the demand for more 4K UHD broadcasting continues to grow, Canon is constantly developing high-quality products to provide producers and broadcasters with outstanding optical performance,” said Yuichi Ishizuka, president and COO, Canon U.S.A. “The CJ45ex9.7B and CJ45ex13.6B both support a variety of broadcast applications, enabling users to capture breathtaking 4K UHD image quality in a form factor that is both lightweight and compact.”
The CJ45ex9.7B and CJ45ex13.6B both employ Canon proprietary optical design technology that features optimal lens positioning using both fluorite and Ultra-low Dispersion (UD) glass. The use of these lens elements reportedly enable users to capture high-quality 4K UHD imagery from the centre of the imaging field to the periphery and across the entire zoom range, making them ideal for a variety of shooting situations—from close-up shots all the way to wide shots such as panoramic views of large venues.
The CJ45ex9.7B 4K UHD is scheduled to be available in April 2018, while the CJ45ex13.6B will be available in May 2018.
