The Ulanzi S-63 Rotatable Horizontal-to-Vertical Mount Plate Kit is the ultimate orientation-switching accessory for select Sony full-frame mirrorless cameras, including the a7 IV, a7R V, a7S III, FX3, and more. Precision-engineered from lightweight aluminum alloy, it delivers a smooth, stable 180° rotation that keeps the center point of your lens perfectly unchanged — so you can switch from landscape to portrait without ever needing to recompose your shot.
Built around an Arca-type quick release base and featuring a generous 2.5″ inner ring diameter, the S-63 accommodates a wide range of Sony and third-party lenses with ease. Silicon-tipped supports minimize vibration during use, while multiple mounting threads — one 3/8″-16 and four 1/4″-20 female threads — provide maximum flexibility for rigs, tripods, and accessories.
