Sony A7 IV underwater housings
Two Salted Line housings fit the Sony A7 IV. Both are rated to 40 m / 130 ft, take the same 90 mm bayonet ports, and share the built-in leak sensor, dual fibre-optic ports, interchangeable port system and reinforced metal base plate.
They differ in the controls they reach and the accessory ports they carry. Pick the one that matches how you shoot — the ports and gears you already own fit either.

Reaches every camera control except the joystick and the Still/Movie/S&Q dial, with buttons 50% stiffer for surer feedback.
