BEC- Hot Shoe Adapter for accessory mounting.
BEC Lectrosonics Hot Shoe Adapter Plate
MPR Says: "Useful Tool"
"This useful Adapter plate has a strong bracket. It’s quite useful because you can place the wireless receiver out of the way of camera operation. The hot shoe adapter plate works great on large cameras such as the EX1 and mostly ENG Cameras. You can also attach a microphone or light to it. Build yourself a well balanced rig with this useful mounting accessory."
