I Purchased This Shoulder Plate To Replace My Zacuto Plate.The Main Reason Was Adjust Ability. To Get My Sony FS7 Further Back On The Plate And Have More Control With The Handles. i Found Setting Up Alot More Quickly. I Thought Initially The Shoulder Pad Was Going To Be An Issue For Comfort, Just Pressing One finger Into The Shoulder Pad Was Too Easy But Once On The Shoulder It Is Comfortable Because All The Shoulder Mount Comes Into Contact At Once. The Smallrig Sliding Plate Comes In Handy To Fine Tune The Camera Balance While On The Shoulder. The Sony VCT Tripod Adapter Works Well With A Solid Click And NO Movement Once Locked Down. Front 15mm Rod Height Bracket Adjustment Is Good And The Bracket Can Be Flipped So Lens Support Brackets Of Various Designs/Heights Can Be Used.The Shoulder Bracket Takes Plain Ended 15mm Rods. I Think Smallrig Could Make Another Pair Of Forward Reaching Arri Rosette Brackets That Go Further Forward.Well Designed, Worth The Money, Does The Job Well.
