Nauticam Upgrade Kit for NA-GH3 (17703) Housing for use with GH4 Camera

Convert your existing GH3 housing to GH4! GH4 is one of the most exciting cameras we've seen in a while, recording 4k video internally to SDXC cards, and featuring some very cool "Varispeed" 96fps modes allowing slow motion capture. This might be the best enthusiast video system available now, and it isn't a bad still photo rig either.
