Godox S-R1 Round Head Adapter

Attaching quickly via a thumbscrew, the Round Head Magnetic Modifier Adapter from Godox is the base component of a magnetic system that attaches simply and quickly to square-shaped speedlights from Godox, Nikon, Canon, and Sony.
The modifier holds your speedlight securely by employing texturized rubber on its top and bottom.
Separately available accessories such as barndoors, dome, honeycomb grid, snoot, bounce card, and filters attach quickly to the front of the adapter via magnets.
