Salted Line CH A7SIII Underwater Housing for Sony A7SIII Cameras | 6'' Long Flat Port | Optical Glass | White
90mm Bayonet|40m/130ft|6'' Long Flat Port|Optical Glass|White
The Salted Line A7SIII Housing with a 6-inch Optical Glass Long Flat Port bundle supports the Sony A7SIII camera with a wide range of standard zoom E-mount lenses, enabling full manual zoom control throughout the lens's range. It is also compatible with a few prime lenses (autofocus only, manual focus not available).
Flat glass ports are ideal for both prime and zoom lenses when shooting at the water's surface. While they can be used underwater, keep in mind that flat ports can reduce your lens's angle of view by up to 28%. For optimal results with wide-angle and fisheye lenses, we recommend using a dome port instead.
This housing provides full control of all camera functions (excluding the joystick) and is equipped with a standard bayonet mount featuring a 90mm diameter, compatible with a wide range of Sea Frogs dry flat and dome ports (except those made for A6xxx and RX1xx camera housings).
The control buttons feature a 50% increase in spring stiffness, providing superior tactile feedback for precise control. Whether you're into underwater or surf photography, this housing offers enhanced durability, functionality and precision, making it the ideal choice for users seeking to capture stunning images in challenging environments.

FAQ
The Salted Line housing is rated for depths of up to 40 meters (130 feet), ensuring reliable underwater performance.
The housing uses a 90mm bayonet mount, compatible with all Salted Line / Sea Frogs dome and flat ports for that bayonet size.
No port is included. Ports are sold separately.
Inspect and lubricate the O-ring before every dive. Replace O-rings at least once per year or every 50 dives. Use only Salted Line / Sea Frogs silicone grease — third-party greases may cause leaks.
