The HJ40ex10B EPF Lens with 2x Extender from Canon is a high-definition EFP lens ideal for field production applications with ENG cameras. It can extend to 770mm with the 2x extender. A unique optical image stabilization system makes possible the capture of rock-steady, high-definition imagery under the most adverse of field conditions.

The optical and mechanical design innovations of the lens substantially reduce flare, veiling glare, and any internal reflections. They also work to minimize image ghosting and other highlight-related chromatic distortions caused by strong light sources on-axis and off-axis, further extending the operational contrast range of the lens.
