To use the DMC GX 80 / 85 as a video camera I had to do some customisations.
I bought an original SmallRig but found the perfect hand grip in a product made by the German company Kilfitt in the 1960th. The grip has a shutter release trigger which ends in a mount for a mechanical remote cable. Also, it has an adjustable metal shoulder rest and a shoulder strap made of leather. The stuff from Kilfitt is intelligently conceived, is build out of high-quality material and can be completely disassembled.
For the transition between the mechanical remote cable and the camera release button, I devised a special adapter which can be used on the SmallRig. And my personal Gyro Gearloose builds the adapter for me in an extremely limited edition of one piece.
For my lovely Zhongyi Speedmaster 0,95/25mm I found the perfect fitting focus levers in Super8 stuff from Ewa Marine.
And for a better view, I bought the Tarion TR-V2.
The whole stuff can be used on every other camera with a rig.
