weird to see an electrical only these days. more common to see optical only.

The Sony A7/A9 series don't have a built-in or bundled clip-on flash, so the SeaFrogs housings ship with an electrical bulkhead that plugs directly into the hot shoe. Their A7S III housing does have optical ports that are aligned to work with a simple trigger that they sell for $20, in addition to the normal electrical bulkhead.
