Once you get used to the idea of shooting video with a DSLR like the Canon 7D, you next want to get the camera off the tripod and move around. The next thing you want is a way to stabilize the jittery video. But, get prepared for a workout.
The following video contains a single continuous shot lasting for almost 3 minutes. I used a hand-held camera stabilizer without a vest system and experimented with various grips and test shots in Grand Central. I really felt it in my arms afterwards. More details coming.
