The SmallRig BSA2355 Lens Adapter Support for Sigma MC-21 Lens Adapter is a support foot to relieves pressure from the camera's lens mount by reinforcing the lens from below, which prevents the adapter from twisting.
The support attaches to the front of the S1/S1R Cage 2345 and L Bracket 2354 via two m4 screws and attaches to the bottom of the Lens adapter via a 1/4 screw. The bottom features a 1/4"-20 threaded hole for mounting tripod plate with the threaded hole on the bottom of the cage, to keep your setup balance when using a cinema lens.

- Supports Sigma MC-21 Lens Adapter (EF to L mount)
- For Smallrig S1/S1R Cage 2345 and L Plate 2354.
- 1/4"-20 Tripod Mounting Holes on the Bottom.
