SINGAPORE – Canon announced the launch of two new portable 4K broadcast lenses that support the use with 4K broadcast cameras employing 2/3-inch sensors: the CJ45ex9.7B, which achieves the highest zoom ratio1 in its class, and the CJ45ex13.6B, which realizes both the highest zoom ratio and longest focal length in its class1.
The new CJ45ex9.7B and CJ45ex13.6B are portable zoom lenses that feature high optical performance, achieving a 45x zoom ratio, and long focal length ranges of 9.7 mm to 437 mm and 13.6 mm to 612 mm, respectively. Both lenses are ideal for broadcasting events such as sports and concerts, where there are frequent opportunities for wide-angle and telephoto shooting. In particular, the CJ45ex13.6B is also well-suited for mid-size broadcast vans and surveillance applications. In addition, both lenses employ a built-in 2x extender that shifts the entire focal length range towards the telephoto end, increasing the maximum focal length at the telephoto end of the CJ45ex9.7B to 874 mm and the CJ45ex13.6B to 1224 mm for even further telephoto shooting.
