90mm Bayonet|40m/130ft|67mm Thread Short Flat Port|Optical Glass|Black

The Salted Line A7IV Housing with a 67mm-thread Optical Glass Flat Port bundle is designed for use with the Sony A7IV camera. It supports a variety of zoom and prime E-mount lenses, providing zoom or focus functionality for some of them.

The 67mm thread also supports the attachment of "wet" close-up and wide-angle lenses for underwater use.

Please note that when using certain lenses - including those paired with ultra-wide-angle "wet" optics - a slight vignetting effect may occur.

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.
