The used DJI R Lens-Fastening Strap secures the camera and lens better for a more stable shooting experience with the following gimbals:
RS 2, RSC 2, Ronin-S, and Ronin-SC. It’s also a required accessory for using SuperSmooth mode on the RS 2 and RSC 2 gimbals. Via an included knob, the strap tightens around the lens and is adjustable to support most lenses.
