I have one Element Technica baseplate/riser for the Sony F3 (as seen on Abel's site here: http://www.abelcine.com/store/Element-Technica-EL-SF3A-RSPK-Sony-F3-Riser-and-Shoulder-Pad-Kit/). Utilizes 15mm rods at 60mm spacing. Has removable shoulder pad which ingeniously holds on with magnets. Great condition - PM me if you have any questions. $300 plus shipping....
