Sea Frogs Salted Line Underwater Camera Housing for Sony A7III/A7RIII | 4'' Flat Port | Black

90mm Bayonet|40mm/130ft|4'' Flat Port|Optical Glass|Black

The Salted Line housing for Sony A7III and A7RIII cameras is part of a new series of hybrid housings designed for underwater photography. Tough enough to withstand the ocean's raw power, including big waves and rough shore breaks.

The Salted Line A7III/A7RIII Housing with a 4-inch Optical Glass Flat Port bundle is designed for use with the Sony A7III or A7RIII camera. It supports a range of zoom and prime E-mount lenses, providing zoom or focus functionality for some of them.

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 a flat port can reduce your lens's angle of view by up to 28%. For optimal results with wide-angle and fisheye lenses, a dome port is recommended instead.

Thanks to its compact dimensions and lightweight design, the 4-inch glass flat-port bundle is the most travel-friendly option available.

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).

How deep can it go?

The Salted Line housing for Sony A7III and A7RIII cameras is rated for depths of up to 40 meters (130 feet), ensuring reliable underwater performance.

The Salted Line A7III and A7RIII 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.

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 Sony A7III and A7RIII cameras users seeking to film stunning footage in challenging environments.
