Compared to SLR MDX-850 camera housing, the MDX-Z7/6 is 100g/3.5oz lighter in weight on land. Weight: MDX-Z7 2700g/95.2oz (on land), MDX-D850 2800g/98.8oz (on land).
Ports and gears for the MDX series SLR housings can be used.
The MDX-Z7/6 is compatible with the system chart for the MDX series SLR housings. You can utilize F-mount lenses with the mount adapter FTZ and ports/gears for the MDX series housings.
Compatible with Optical YS Converter/N1. TTL strobe photography possible.
An optional Optical YS Converter which converts the camera’s hot-shoe TTL signal into an LED light signal is compatible with the housing. Manual strobe photography is also possible.
Designed for both F mount lenses with the mount adapter FTZ and Z mount lenses.
The Focus/Zoom dial has two gears, one for F-mount lenses with the mount adapter FTZ and the other for Z mount lenses. The MDX-Z7 has been designed to take into consideration various Z mount lenses which will soon be available.
The camera’s upper control panel can be seen.
A window for the camera’s upper control panel is also incorporated. As brightness of the camera’s upper control panel has increased, the visibility is now greatly improved.
