The Canon CJ20EX7.8B is a portable 20x zoom lens for professional 2/3″ video cameras. Designed for 4K image capture, the CJ20EX7.8B provides optimal reproduction for shots ranging from establishing vistas to revealing closeups. This model can be used in a variety of production applications, including narrative projects and broadcast sports coverage. The focal-length range is 7.8-156mm with a minimum object distance of 2.6′. The lens maintains its 4K performance even when using the built-in 2x extender (for a maximum range of 15.6-312mm). The lens is designed with aspheric elements to minimize monochromatic and chromatic aberrations, even at wide focal lengths. It has a focus barrel with 170° of rotation, enabling quick, accurate focus pulls. This lens works with standard Canon-compatible zoom and focus control systems.

The CJ20EX7.8B’s digital drive unit features three highly accurate FIZ (focus/iris/zoom) data encoders which can be connected to support virtual/compositing systems. The drive unit’s encoder does not require initialization upon powering up, enabling a quick shooting start. Weighing under five pounds, the CJ20EX7.8B’s center of gravity is closer to the lens mount for better balance, and reduces stress on the operator’s hands. For easier operating, this zoom also features a Basic Mode with a simplified display.
