The Sea Frogs A7SIII Salted Line camera housing in white is waterproof up to 40 meters / 130 feets tailored for the Sony A7S III. Its 4' glass flat long port supports manual focus with Sony FE 90mm f/2.8 macro and Sigma 35mm f/1.4 DG Art E-mount lenses. It's also compatible with various E-mount lenses.

SeaFrogs Salted Line A7S III housing lets you control all camera functions (except the joystick) underwater up to 40 meters (130 feet). The standard bayonet with a 90mm diameter allows for using any Sea Frogs dry flat and dome ports, except ports designed explicitly for A6xxx and RX1xx camera housings.

The Salted Line A7S III version stands out from the standard Sea Frogs A7S III housing with enhanced features, including two stainless steel latches with locking pins, a larger LCD window, and the capability to mount a detachable 2-stage pistol grip trigger. Notably, the control buttons boast a 50% increase in spring stiffness, ensuring improved tactile feedback. Ideal for underwater and surf photography, this upgraded housing offers enhanced durability and precision for Sony A7S III users. Explore the advanced capabilities of the Salted Line A7S III housing for an optimized underwater shooting experience.
