This adapter has a female hotshoe that will accept a hotshoe-based flash and short cord with a miniphone jack (female). This setup provides a very convenient way to attach a sync cord with the very reliable miniphone plug to a flash unit that does not have a built in sync connector.
This adapter will provide a reliable sync connection for flash units such as the Canon 580EX, 550EX, 430EX, 540EZ, 430EZ, 420EZ, Nikon SB-600, and many other flash units that do not have a sync connector on the flash.
The bottom of the connector provides both male shoe rails and a 1 ⁄ 4 inch - 20 tripod screw. This affords many mounting opportunities including to standard tripods, to other flash shoes, and directly to the very popular umbrella adapters.
This adapter is based on a nice German hotshoe.
The cable is straight and approximately 11 inches long.
Depending on your camera, these would be the two most commonly used cords to attach the flash to the camera:
