The AD-E1 is designed to allow existing Speedlites that have dust- and drip-resistance features to be used with cameras that have the new Multi-Function Shoe. Sturdy design allows for the attachment of large accessories.
The Multi-Function Shoe Adapter AD-E1 is designed to provide sufficient static pressure strength.
This enables the AD-E1 to withstand the weight and stress when paired with large accessories like the Speedlite EL-1.
Sealings at all the connecting points ensure dust- and drip- resistance capability when using existing Speedlites. Some of these include the Speedlite EL-1, 600EX series, and 580EX II, which require this adapter to maintain their dust- and drip-resistance capability on the Multi-Function Shoe.
