The Hot Shoe to 1/4"-20 Screw Adapter from Lastolite allows you to mount accessories with a 1/4"-20 screw thread onto a shoe mount. The adapter fits into an on-camera hot shoe mount or cold shoe accessory mount and provides a 1/4"-20 screw to then place compatible accessories such as a monitor or LED light onto that mount. The adapter features thumb wheel locks to keep the adapter in place on the shoe mount and the accessory screwed tight to the 1/4"-20 screw.
