For fast-moving shoots where you're in the thick of the action and need a small, mobile camera rig, the Man Cam Bundle for Sony FS100 Camera from Letus35 may be just what you're looking for. It has front and rear T-handles that make for a solid, easy grip, and excellent camera control. It's designed for use with a preview monitor rather than an EVF. A custom backpack is included that organizes and protects batteries, remote receivers/transmitters, recorders, etc. and moves a lot of weight off your arms, leaving you with an easy-to-maneuver rig ready for fast action.
Inspired by the military, the Man Cam treats the camera as if it were a machine gun and gives a very unique shooting style, with a half Steadicam/half handheld feel. It's easy to boom up and down while walking and it's balanced for a smooth shot. The Man Cam is also a great set-up for camera operators who have long shoot days and need to prevent arm fatigue.
