GH4 SpeedBooster for Canon EF Lenses with Wireless Focus Control
This is pretty damn cool. Aputure are coming out with a GH4 SpeedBooster adapter for Canon EF lenses that incorporates wireless focus control with a range of 328 feet.
I am not crazy about the current focus controler, but I've heard that Aputure are working on something more like the traditional focus-pulling knob with interchangeable white marking rings.
