The PZ-E2B Power Zoom Adapter from Canon enables complex zoom control for the RF 24-105mm f/2.8 L IS USM Z lens.
Zoom speed of the DC motor can be adjusted via a dial in a stepless manner to allow rapid and low-speed zooming. The PZ-E2B draws power from the camera through contacts on the lens. Additionally, a 20-pin port allows compatibility with Canon zoom servo grip, zoom demand, focus demand, and other accessories for movie shooting.
