Salted Line CH A7SIII Underwater Housing for Sony A7SIII Cameras | 4'' Long Flat Port | Optical Glass | Orange

90mm Bayonet|40m/130ft|4'' Long Flat Port|Optical Glass|Orange

The Salted Line A7SIII Housing with a 4-inch Optical Glass Flat Port bundle is designed for use with the Sony A7SIII 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).

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 A7SIII 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.
