When you purchase a new camera flash unit, there are usually a few items you need to round out the flash's included accessory package. With that in mind, B&H Photo
has put together this Accessory Kit
to make your picture taking experience more productive.
In addition to the standard accessory package that is included by the manufacturer with the Canon 580EX II Speedlite TTL Shoe-Mount Flash, this kit includes a Stroboframe Pro-RL Bracket, and an off-camera shoe cord.
