The new FourSquare speedlight adapter is a clever small strobe mount and softbox combo that allows the photographer to mount up to four flashguns into a 30″ X 30″ softbox or an umbrella.
The FourSquare is made of rugged T6061 hard anodized aluminum and you can put this on any stand you want. The first batch of FourSquares will be sold as a complete kit including the mount and softbox.
The complete kit (softbox and FourSquare mount) collapses into a very manageable bundle measuring only 18 inches, just the size to carry conveniently on the plane.
How much? Go on over to their website and inquire. The FourSquare kits are due for release in a few weeks.
