Lanparte MCK-03 kit is designed for Panasonic lumix GH4 and Sony A7 A7II A7S A7SII A7R A7RII serial cameras. It comes with follow focus, matte box, arri style handgrip, shoulder pad, and power supply system. VCT-14 mount underneath the baseplate, so the whole kit can be mounted and removed from the tripod in 1 second. We use the hollow-out design that cuts 1/3 useless weight.Cameraman can use the V mount battery to power the camera via dummy battery pack for long time shooting. Furthermore the whole kit can be put into ABS cage, it's so easy for transportation.
