Vello's Hot Shoe Adapter with PC Socket + Top Shoe allows you to add a PC connection to any Canon camera that does not come with a built-in PC sync connection, while still retaining the existing hot shoe functionality. The top hot shoe supports full E-TTL & E-TTL II metering when used with Canon TTL compatible components.
This adapter does not provide high-voltage sync protection, and is not recommended for use with flash units that have a trigger voltage of more than 6V.
The PC connector can only be used as an output to trigger other off-camera devices. It can not be used to trigger a flash mounted to a shoe positioned off-camera.
