90mm Bayonet|40m/130ft|6'' V1 Dome Port|Acrylic|Orange

The Salted Line A7IV Housing, bundled with a 6-inch or 8-inch Optically Correct Acrylic or Glass V1 Dome Port and a compact 23mm extension adapter ring, supports a range of wide-angle zoom and prime E-mount lenses.

This housing provides full control of all camera functions (except the joystick and Still / Movie / S&Q dial) 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.

The Salted Line A7IV Housing version offers several upgrades over the standard Sea Frogs housing, including:

  • Enhanced Security: Durable stainless steel latches with locking pins.
  • Improved Visibility: Larger LCD screen window improves visibility.
  • Precision Control: Compatibility with a detachable 2-stage shutter grip trigger.

Frequently Asked Questions

How deep can it go? +
The Salted Line housing is rated for depths of up to 40 meters (130 feet), ensuring reliable underwater performance.
Acrylic vs Glass +
Acrylic ports deliver solid image quality in most scenarios, and they have the advantages of being lighter, more affordable, and easier to repair. Glass dome ports, while offering slightly superior image quality in specific conditions and better scratch resistance, cannot be repaired if scratched.
6" vs 8" +
The 6" domes deliver excellent image quality in most shooting conditions while being significantly more compact and travel-friendly, making them the preferred choice for many users. While 8" domes can offer slightly improved edge sharpness, their larger size makes them bulkier and less convenient to transport.
What is Surf Edition? +
Dome Ports include a lens shade that protects them from accidental contact with objects during use and offers benefits in some shooting conditions. The Surf Edition Dome Ports are designed without a lens shade to minimize drag when shooting in large waves.
What dome and flat ports are compatible? +
The housing uses a 90mm bayonet mount, compatible with all Salted Line / Sea Frogs dome and flat ports for that bayonet size.
Does it include a port? +
No port is included. Ports are sold separately.
What O-rings and maintenance is required? +
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.
Can I connect an external strobe without an optical cable? +
The housing features a standard Synchro cable port for direct strobe connection, in addition to dual fiber-optic ports (Sea&Sea type).
Does the shutter grip come included? +
No — the detachable shutter grip with two-stage trigger is sold separately.
