HD ETTL Off-Camera Cord f/Sony

 These
are the perfect answer to using a dedicated flash unit off of the
camera and yet retain all of the dedicated features of the flash.

These heavy duty TTL cords are designed to fit Sony a Series Digital SLR cameras that use dedicated flash units. They feature a molded shoe on
one end that slides onto the camera hot shoe and locks to prevent
accidental dislodging of the shoe. A second shoe mounts onto a flash
bracket or light stand via either a standard foot with lock or a 1/4-20
thread. The top of the shoe accepts the flash unit. A heavy duty 3 foot
coiled cord connects the shoes.
