With its two handles and solid construction you'll have no trouble keeping your phone still while filming. Smooth pans aren't a problem, either.
The adjustable clamp that holds your phone can accommodate iPhone and Android handsets of all sizes. There's also room on the rig for mounting a light or a microphone.
Just make sure you don't cover the camera lens or flash with the clamp. And avoid putting the clamp on any side-mounted controls!
The scaled-down Shoulderpod S1 is just the clamp, a small handle and an arm strap. It still keeps your phone steady, but has a much more portable design.
If you remove the handle, you can attach the clamp to any standard tripod.
The various parts are eye-catching and built of metal or wood. The modular design lets you build the solution you want. There's even a "cold shoe" mount (bottom left corner) for attaching accessories.
