Canon announces the CJ15ex4.3B, a 4K broadcast portable zoom lens with class-leading magnification and wide-angle focal length. With viewer demands for 4K content rising, the new Canon CJ15ex4.3B is the ideal choice for broadcasters looking to future-proof their content when upgrading to 4K systems and workflows. The lens, the first of this type to use ASC, will be on display at IBC 2019.

The new CJ15ex4.3B 4K broadcast lens expands Canon’s series of industry-leading 4K broadcast lenses for 2/3-inch sensor cameras. Offering the outstanding optical performance known of Canon’s UHDxs series, the class-leading CJ15ex4.3B supports a maximum zoom of 15x and a wide-angle focal length of 4.3mm. Now a Canon lens for every broadcast filming scenario, this lightweight (2.19kg) and compact lens enables broadcasters to achieve 4K optical performance, even with its built-in 2x extender, ensuring footage is of the highest resolution – from the centre of the image to the very edges.

The launch of the CJ15ex4.3B continues the manufacturer’s long-standing commitment to supporting the industry with innovative and optically excellent products. With faithful colour reproduction, the lens supports BT.2020 camera chromatic aberration correction when attached to a compatible 4K camera. Going one step further than the conventional broadcasting standard of ITU-R Recommendation BT.709, using the CJ15ex4.3B broadcasters can achieve a wider colour gamut. Such lens capabilities result in brighter, more vivid and life-like images with outstanding tonality, realistic texture and depth – meeting the consumer demand for more immersive broadcast viewing experiences.

The optimized arrangement of fluorite, UD and Super UD lens elements used in the CJ15ex4.3B also corrects chromatic aberrations optically. Using this Canon-developed technology, the lens produces beautiful images with less colour blur or colouring around the outlines. It’s also the first portable broadcast lens to feature ASC (Air Sphere Coating) – a new technology that applies a coating which suppresses the reflection of the light – reducing ghosting intensity and achieving a more authentic HDR shooting.

CJ15ex4.3B Key Features:

  • Class-leading magnification (15x) and widest angle (4.3mm) in a portable wide-angle zoom lens
  • 4K resolution from center to the edge of the lens
  • ASC Coating Technology
  • UD and Super UD lens elements
  • BT.2020 Wide Color Gamut and High Dynamic Range support
  • High-Performance Digital Drive unit (e-Xs IV)
  • Light and compact body for excellent mobility
  • Built-in 2x extender
