Sea & Sea MDX-a7II Underwater Housing for Sony a7 II Mirrorless Camera


Designed, engineered, and manufactured in Japan, SEA&SEA's latest mirrorless housing, the MDX-a7II for Sony Alpha a7II, is unmatched in its class.

NEW FEATURES
  • Optical YS-Converter Compatible: Converts the cameras TTL signal to a light signal. Both TTL and Manual Strobe control is compatible with Fiber-Optic Cable II.
  • TTL ON/OFF Confirmation: Indicator Blue light indicates TTL mode activation, and Green light indicates Manual mode activation.
  • Ergonomically Re-designed Levers: Shutter lever, AF mode lever, AF-ON lever, and movie-record lever all have been re-designed with ergonomic shapes.
  • Movable Focus/Zoom Gear: When the Focus/Zoom dial is pulled out, the gear inside the housing will move outward allowing for lenses with large diameter to be easily mounted.
  • Luminescent Buttons: Most levers and buttons will glow in dark environment.
The ergonomic and full-featured MDX-a7II housing allows for operation of the Sony Alpha a7II camera's essential controls in a low profile design. Using the newly developed ML-NX Conversion Ring 30, the MDX-a7II housing is compatible with all of SEA&SEA's premier NX ports in addition to the popular ML Ports.

The MDX-a7II housing accommodates SEA&SEA's exclusive Internal Optical YS-Converter, which eliminates the need for a Sync Cord system. The converter works via the hot shoe to trigger the strobe when the camera's shutter is activated, converting the TTL signal to a light signal. This Fiber Optic system allows for rapid strobe firing, reduced recycle time, and eliminates possible leak points that occur on traditional bulkheads.
