With wired flash system accessories, you can easily set up a TTL wired autoflash system with any EOS camera.

Up to four Speedlites can be connected in a wired flash system. Any EOS dedicated EX-series, EZ-series, EG-series, and E-series Speedlite can be used.

Connection and set-up

Use the necessary wired flash system accessories to connect the Speedlites and take the picture after the pilot lamp lights.

• If the TTL Hot Shoe Adapter 3's battery power is very low, the Speedlite's flash-ready indicator will not light and no flash will be fired. Check the TTL Hot Shoe Adapter 3's battery level before using it.
• Do not extend the Connecting Cord length by more than 9 meters (3 - 300 cm cords connected together)
