Salted Line CH FX3/FX30 Underwater Housing for Sony FX3/FX30 Cameras | 4'' Long Flat Port | Optical Glass | White

90mm Bayonet|40m/130ft|M33 Bulkhead|4'' Long Flat Port|Optical Glass|White

The Salted Line FX3/FX30 Housing with a 4-inch Optical Glass Flat Long Port bundle supports manual focus for the Sony FE 90mm f/2.8 Macro and Sigma 35mm f/1.4 DG Art E-mount lenses. It is also compatible with a variety of other zoom and prime E-mount lenses.

Flat glass ports are ideal for both prime and zoom lenses when shooting at the water's surface. While they can be used for underwater photography and videography, keep in mind that a flat port can reduce your lens's angle of view by up to 28%. For wide-angle and fisheye lenses, a dome port is recommended instead.

This housing provides full control of all camera functions (excluding touch screen) 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 FX3/FX30 Housing version offers several upgrades over the standard Sea Frogs housing, including:

  • HDMI Support: Integrated M33 threaded bulkhead interface for external monitor connection
  • Improved Visibility: A larger LCD screen window enhances visibility.
  • Precision Control: Compatibility with a detachable 2-stage shutter grip trigger.
