Canon CJ12ex4.3B, 4K
CJ12ex4.3B portable 4K 2/3-inch broadcast lens, the world’s first* 4K wide-angle lens with for use with 4K broadcast cameras featuring 2/3-inch sensors.
This will be the first in a new line of 4K broadcast lenses intended to support a range of 4K ultra-high-definition (UHD) productions.
Designed as a portable wide-angle 12x zoom lens, the CJ12ex4.3B is ideal for Electronic Field Production (EFP) and Electronic News Gathering (ENG) broadcast applications covering news, sports, live events and filmmakers creating documentary projects desiring 4K quality. Canon is also developing a portable, longer-zoom 4K lens that will further extend 4K UHD production capabilities….
This portable wide-angle lens provides the optical excellence needed for 4K broadcast production. Its 4.3mm wide angle (96.3 degree horizontal angle of view) and minimum object distance of 30 cm are both the best of its class in the world*. A built-in 2x extender allows more telephoto operation without sacrificing 4K image quality.
This wide angle lens supports framing of scenes containing large amounts of image detail — for example, a wide end zone-to-end zone shot. Editors can then select a 1920 x 1080 crop from within the 3840 x 2160 camera original with full HDTV image quality. Alternatively, the 4K UHD camera video can be downsampled to HDTV offering enhanced resolution by virtue of that supersampled original.
The form factor for production shooters will be very similar to shooting with Canon’s HD lenses in size, weight and controls. Its light weight of 4lbs, 10oz. and compact size make it ideal for shoulder-mounted ENG applications.

Canon launches world’s widest 2/3” 4K portable broadcast lens¹ – the CJ12ex4.3B
London, UK, 25 August 2015 – Canon today unveils the CJ12ex4.3B, a new 2/3” portable 4K zoom lens with the world’s widest focal length – an incredible 4.3mm, designed for professionals shooting interviews or live broadcast, including sport and news. Canon also today announces that it is developing a new compact 2/3” 4K all-purpose-zoom lens. Further bolstering Canon’s 4K broadcast lens range for cameras employing 2/3” sensors, the versatile new lens will be optimised for both indoor and outdoor shooting, across a variety of applications including, sporting events, live broadcasts, as well as television dramas and commercials.
4K all-purpose-zoom lens
Outstanding 4K optical performance
Leveraging Canon’s renowned heritage in optical design and advanced technologies, the CJ12ex4.3B delivers outstanding 4K image quality throughout the entire 12x optical zoom range. Providing the freedom to quickly adapt to different shooting environments, the new lens enables shooters to swiftly move from an ultra-wide 4.3mm angle shot to close ups, whilst ensuring first-class image quality from the very centre to the edge. A built-in 2x extender also helps provides even greater focal reach, whilst still maintaining 4K optical performance.

To further provide sharp, high contrast images, the CJ12ex4.3B includes an increased use of fluorite and UD glass combined with Canon’s expert coatings, resulting in exceptional control over ghosting and flare. A new three group internal focus system also reduces focus breathing.
Exceptional portability and flexible operation
Boasting a brand new design, the CJ12ex4.3B is compact and lightweight, weighing just 2.1kg, making it similar in size and weight to a comparable 2/3” HD lens. Ideal for on-shoulder shooting traditionally adopted by news gatherers, the lens can easily be used on-the-go, and with an ergonomic design and grip, it is comfortable to hold for longer periods of time. The lens also incorporates three 20-pin connectors for easy integration with existing HD zoom/focus controllers and can be directly connected to an external virtual operation system at the same time.

Featuring a Digital Drive Unit, the CJ12ex4.3B offers advanced operability giving users the freedom to select repeatable zoom positions and speeds, in addition to focus and iris settings. A 16-bit absolute value encoder integrated into the Digital Drive Unit allows operators to start shooting with the camera’s aberration compensation function in an instant, without the need for any initialisation. This is perfect for news and wildlife environments where action can disappear as quickly as it started. A digital display, built into the Digital Drive Unit, also makes it easy to set, review and adjust vital functions in a way similar to 2/3” HD lenses.
