If you are looking to take your Panasonic DMC-GF1 into the depths then your going to need a special rig that can do the job.
Please step forward the Waterproof INON X-2 case, specifically designed to house the Panasonic DMC-GF1 in a watertight corrosion-resistant alloy case capable of depths up to 75 meters.
The rig is fitted with two under water lights so there’s no excuse not to go filming in those under water caves. But be aware this under water housing doesn’t come cheap. The full rig will cost approximately $2,430 : $2,200 for the camera case and and extra $115 for each grip.

Inon compatible flash Z-240, D-Series 2000, S-2000, D-series 180, Z-220 series.
