*note* - Arca Swiss plate and Manfrotto clamp not included :p. Compatable with Manfrotto 725B tripod heads and other models with the same clamp. This small and light weight adapter allows you to secure your Arca Swiss quick release plate (that attaches to your camera) into a Manfrotto tripod clamp. If you are into photography like I am, then I am sure you can understand how much of a pain it is to constantly be screwing on and off various quick release plates in order to use your favorite camera accessories. This adapter is the fast solution to that problem! Just slide the Arca Swiss plate into the adapter, and lock into your Manfrotto clamp.
