The Tiffen Stedicam Curve for GoPro and Smoothee for smartphones bring the awesome power of a Steadicam to your hand-held video footage. Both rigs have a handle that acts independent to the weighted mount. You make tiny adjustments with your index finder and thumb.
It takes a little practice, but soon you’ll be shooting video like a pro without the tell-tale signs of footage bobbing up and down associated with hand held video.
The Stedicam Curve will cost you $100 while the Smoothee will set you back $150.
