Salted Line CH A7SIII Underwater Housing for Sony A7SIII Cameras | 6'' Medium Flat Port | Optical Glass | White

The Salted Line A7SIII Housing with a 6-inch Optical Glass 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.

The Salted Line A7SIII Housing version features several premium upgrades, 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.
