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 metering when used with Canon TTL compatible components. Additionally, this adapter can also be used to provide a PC connection to flashes that don't have one, when used off-camera.

Note! 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.
