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 center 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.
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 initialization. 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.
The CJ12ex4.3B lens is not alone, though. 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 optimized for both indoor and outdoor shooting, across a variety of applications including, sporting events, live broadcasts, as well as television dramas and commercials. Canon will exhibit the lens for reference at the 2015 Beijing International Radio, TV & Film Exhibition (BIRTV), to be held from August 26 to 29 in Beijing, China.
Like the new CJ12ex4.3B wide angle zoom lens, the new 4K portable zoom lens under development will realize a high level of imaging performance supporting use with 4K broadcast cameras employing 2/3-inch sensors while also featuring a weight and body size that achieve the same level of mobility as conventional portable HDTV lenses.
Canon aims to commercialize the new 4K portable zoom lens in the first half of 2016. In addition to its HDTV broadcast lens and 4K Cinema Lens lineups, the company will further strengthen its 4K broadcast lens lineup to respond to the needs of a wide range of users.
