The Canon PZ-E2B power zoom adapter has a 20-pin remote connector and USB-C, giving the RF 24-105mm F2.8L IS USM Z and RF 70-200mm F2.8L IS USM Z motorised zoom for video. The 20-pin connector takes Canon's ZSG-C10 zoom servo grip for ENG-style work, the ZSD-300D zoom demand and the FPD-400D focus demand. It also outputs real-time lens metadata for VFX and virtual production.

A DC motor and gear reduction mechanism drive the zoom. W and T buttons control it. Without a zoom demand connected, a dial sets the speed: with the RF 24-105mm F2.8L IS USM Z, approximately 3 to 90 seconds in Normal Mode, or approximately 1.5 to 90 seconds in High-speed Mode with external power through USB-C (the USB power adapter is sold separately). A switch selects servo or manual zoom, and compatible cameras can assign zoom to their own custom buttons or run it remotely through Camera Connect, EOS Utility, Browser Remote or the XC Protocol. The adapter attaches with three screws and doesn't need special tools, even with the lens on a rig, gimbal or tripod. It measures approximately 105 x 81 x 60 mm and weighs approximately 165 g, adapter only.
