Im currently on a show that requires A Camera to convert to Steadicam. Ive purchased the Betz handheld rig that allows you to take the camera with the steadicam plate and mount directly to handheld mode. I also have the Betz tripodlockplate that allows you to mount to your existing head.
The shoulder mount has a pitch adjustment for your shoulder, baby pin receiver, the pad rotates forward and aft and the rosettes can accept several versions of existing grips. You have to tell Betz what brand you have or you can use theirs. It's a great setup. Well made and the support from Munich is amazing.
The photo is a Sony Venice with an Arri Signature full frame 35mm prime with shape handles.
I'm a fan.
