SmallRig L-Bracket for SONY Alpha 7S III Camera 3003 attaches to the camera using a 1/4"-20 screw, with an anti-twist design and rubber pad preventing wiggles or scratches. Both the side plate and base plate are Arca compatible, allowing a quick switch between horizontal and vertical orientation shooting. The L-Bracket does not block buttons, ports, LCD screen, or battery switches of the camera. The whole L-Bracket can extend to the left by 20mm if you need more room for tethering or cable release. It also comes with 1/4"-20 accessory threads allowing mount of accessories, such as SmallRig Cable Clamp 1822, or SmallRig Cold Shoe Mount BUC2736. A flat-head screwdriver is kept on the base plate for easy access.
