Most Anticipated Housing Since MDX-D300

SEA&SEA announces the MDX-D500 Underwater Housing for the Nikon D500 camera, the most anticipated housing since the MDX-D300. Newly designed features of the MDX-D500 housing greatly surpass its predecessor. New features include the compatible internal Optical YS Converter of the MDX-D500 versus the external TTL converter connector of the MDX-D300. The MDX-D500 housing also has redesigned levers and luminescent buttons that increase their visibility while shooting in low light conditions.
The main command dial is located on the right-hand side of the housing. The sub-command dial is also located close to the shutter release lever, allowing for easy access of both controls. The camera's diopter adjustment dial can be operated from the housing. This feature is effective when two or more people (with different eyesight) use the housing. When the focus/zoom dial is pulled out, the gear inside the housing will move outward allowing for lenses with large diameters to be easily mounted.
