Fixed with a mini articulated arm on a video butt support, it can target in much better conditions than the screen of the camera (more reflections) or viewfinder (too far).
+ Has a standard 12 volt outlet.
+ Good battery with a battery (approximately 3 hours).
+ It provides the "peaking" which allows perfect focus.
- The definition is as good as the screen of the camera (Sony RX10).
- Rubber Lœilleton is comfortable having shortened the short end.
