An accessory shoe adapter is provided for video cameras having a battery pack mount with a pair of contacts adapted to receive a battery pack to power the camera. The adapter comprises an adapter body having a front and a rear and includes a shoe portion for mounting an accessory; a camera mount formed on the front of the adapter body and adapted to be mounted on the battery pack mount of the video camera; and a battery pack mount formed on the rear of the adapter body and adapted to receive the battery pack. A first pair of electric contacts is provided in the shoe portion, a second pair of electric contacts is provided on the camera mount of the adapter body corresponding to the electric contacts provided on the battery pack mount of the video camera, and a third pair of electric contacts is provided on the battery pack mount of the adapter body at locations corresponding to the second pair of electric contacts on the adapter body camera mount. The second and third pairs of electric contacts on the adapter body are interconnected, as are the first pair of electric contacts in the shoe portion and the third pair of electric contacts on the adapter body battery pack mount. The adapter is engaged to the video camera by mounting the adapter body camera mount on the video camera battery pack mount, and a battery pack is installed by engaging its contacts with the adapter body battery pack mount. Because of the interconnection between the first and third pairs of adapter body electric contacts, the same battery pack may also be used to power an accessory mounted in the shoe portion of the adapter.
