SmallRig 6313 is a hot shoe mount monitor mount that supports horizontal and vertical shooting. The tilt stiffness is adjustable without tools.

SmallRig 6313 is an adjustable mount designed for camera monitors, wireless video transmitters, and other accessories. It securely attaches to the cold shoe of your camera or camera cage and allows you to quickly flip the monitor between landscape and portrait shooting.
The 1/4"-20 mounting screw at the top of the holder is surrounded by recessed guide pins. These lock into the base of a compatible monitor and prevent the device from rotating or loosening during use. The arm rotates a full 360 degrees around its axis and tilts 180 degrees. This model is designed with vertical shooting in mind: the monitor can be rotated to a vertical position (e.g. for shooting vertical videos) while the tilt adjustment still functions normally.
The tilt friction and damping can be easily adjusted using the thumbscrew on the side, completely without tools, making it easy to balance monitors of different weights. The accessory shoe mount is locked in place with a tightening ring, and there is an additional 1/4"-20 threaded hole on the bottom of the stand, which can also be used to attach the holder to various articulating arms (magic arms).
