Z-E2 Power Zoom Adapter
The Canon PZ-E2 Power Zoom Adapter helps you achieve smooth and precise zoom in video. The zoom speed can finely adjusted using a dial and can be further moved from Normal Mode to High-speed Mode when externally powered via USB power adapter PE-E1 (sold separately).
The PZ-E2 can be easily attached and detached without any special tools needed. Once aligned to the lens sockets, the mounting screws can be simply fastened with a coin. The adapter can also be attached and detached while the lens is combined with a rig, gimbal or tripod, meaning you don't have to re-arrange your system.
Note: The PZ-E2 supports USB type C only, see E2B for 20-pin ports.
