This handy adapter will let you put multiple accessories on one shoe mount. A simple idea, but hugely helpful when you're trying to run multiple accessories like mics, lights, and monitors on the same camera shoe. Available in two lengths (8" or 4") to meet your needs. It pains me that I have to say this, but just in case.... this rental is for the extension bar only. The cameras/accessories shown in the photos do not come with it.
