Product Overview

Revised ergonomic design, improved safety features and eye-catching exterior. The new MDX-L series housings are now upgraded with more standard features to ensure better handling and greater protection for your camera. Designed for the Sony a7RIV camera, the Sea & Sea MDX-a7IV Underwater Housing comes equipped with Grip Plus, SA8 Fixed Ball Bases, and Leak Sentinel XB. Equipped with new silicone handle inserts for firm and steady grip as standard. Silicone compound material implanted in the grip providing firm hold. SA8 Fixed Ball Bases now comes standard with MDX-L series housings. Leak Sentinel XB, which measures atmospheric pressure inside the housing even on land, is now a standard accessory together with the conventional built-in Leak Sensor. Two alert sensors are available for your peace of mind.

For better noticeability, controls are partially colored with yellow. Compatible with the Sea & Sea, Manual Flash Trigger/S" (optional). The camera can be mounted in the housing with its LCD monitor extended from the camera to reduce the distance between the rear window and monitor to increase visibility. Compatible with Sea & Sea Optical YS Converter S1 which converts the strobe light emission signal of the camera to LED light and synchronizes with the Sea & Sea YS strobe. It is a high-performance converter that does not just emit simple light-emitting signals, but also performs TTL auto light control. * Sony original adapter ADP-MAA is required separately for connecting camera and optical YS converter. With Buoyancy Pocket *1, underwater weight has lessened by 8.5 oz. (240 g). *2. The pocket can be used as space for extra battery pack *3. Sea & Sea will not take any responsibility for accident caused by use of extra battery or any other accessory stored in the buoyancy pocket.

Compatible with all the DX (NX) series ports. The camera can be removed from the housing easily even if a lens with large diameter such as the SEL1635GM is mounted on the camera without removing port from the housing enabling you to replace battery and lens with ease. The Port Lock prevents the port from turning or loosening and the Port Lock lever is specifically located to avoid being unlocked accidentally. The housing is equipped with a lens-lock release button which makes it possible to change lenses easily, without opening the housing. Pulling out the Focus/Zoom Dial gives sufficient room inside the housing to easily accommodate larger diameter lenses.

The camera's diopter adjustment dial can be operated from outside the housing. This feature is useful when two or more people with different eyesight use the housing. All controls have luminescence stickers which glow in dark environment. Equipped with the Optical Viewfinder 0.5x as standard. Other optional viewfinders such as the VF180 1.2x, VF45 1.2x and Optical Viewfinder 0.66x, 0.8x can be used. Some vignetting occurs. When the VF180 1.2x is mounted on housing, the upper part of the camera's viewfinder cannot be viewed due to vignetting. Sync Cord 2-pin Connector enables use of conventional hardwired Sync cable (Manual mode only). The housing body is made from corrosion-resistant aluminum alloy (machined)½and the grip is corrosion-resistant die-cast aluminum alloy. Equipped with two sacrificial zinc diodes (one on the front case and the other on the rear) to prevent electrolysis damage.

Built-in leak sensor immediately alerts you to water ingress. Tripod screw mount is located on the center underside of the housing. Equipped with under guard to protect from scratches. Housing is depth rated to 330' (100m) measures (W x H x D) 13" x 7.4" x½5.2" (330mm x 189mm x 131mm) and weighs 6.2 lbs. (2.8 kg).
