For the RF 24-105mm f/2.8L IS USM Z and RF 70-200mm f/2.8L IS USM Z lenses, the Canon PZ-E2B is the power zoom adapter with a 20-pin remote connector as well as USB-C. The 20-pin port lets Canon's zoom servo grip, zoom demand and focus demand connect to the lens, and Canon lists the ZSG-C10 Zoom Servo Grip for ENG-style operation, along with the ZSD-300D zoom demand and FPD-400D focus demand, as compatible. Canon also states that real-time lens metadata is output from the 20-pin terminal for VFX and virtual production use.

As with the PZ-E2, a zoom speed dial adjusts speed finely, a switch selects servo or manual zoom, and a DC motor with gear reduction drives the lens. Zoom time is 3 to 90 seconds in Normal Mode, or 1.5 to 90 seconds in High-speed Mode when powered externally over USB-C from a separate USB power adapter. It fixes with three coin-tightening screws and can be fitted while the lens is on a rig, gimbal or tripod. Approximate size is 105 x 81 x 60 mm, and weight is approximately 165 g, adapter only.
