Lanparte mirrorless camera kit for GH4 and A7 from lanparte on Vimeo.
Lanparte MCK-03 kit is designed for Panasonic lumix GH4 and Sony A7 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.
