I bought this one http://hipjib.com/?lang=en a few weeks ago. Its great! you can do a lot of stabilized movements with this little thing. I have it always with me in my bag. Sometimes I use it with my small manfrotto monopod, but it takes the Sachtler ACE tripod as well. For small cameras like the A7s, GH4 etc its perfect. Its what the "lone fighters" are looking for.
