SmallRig Rotatable Horizontal-to-Vertical Mount Plate Kit for Canon EOS Specific R Series Cameras is designed to quickly switch between horizontal and vertical shooting without adjusting the lens optical axis. It maintains full access to LCD flip screen and ports and features built-in pads that prevent scratches and twist.

In the baseplate there are QD mount, strap hole for Wrist Strap 3848 and a magnetic dual-head wrench for easy installation and release.
