Key Product Features

• Compatibility: Designed for Sony Alpha 7R V, Alpha 7 IV, and Alpha 7 S III cameras. The kit includes a cage, an HDMI cable clamp, and a top handle for low-angle shots and camera protection.
• Two-point Locking: Securely mounts the camera with an integrated 1/4"-20 screw and two side locking plates (one for Sony Alpha7S III/Alpha 1, one for Alpha 7 IV) to prevent twisting. Note: The camera strap eyelet is occupied when using the side locking plate.
• All-round Protection: Constructed from aviation aluminum with a formfitting design for security and durability. Built-in protective pads prevent camera scratches. Maintains access to camera controls and hot shoe.
• Multiple Mounting Points: Features an integrated shoe mount, multiple 1/4"-20 threads, and 3/8"-16 locating holes for ARRI accessories. Includes a built-in NATO rail and strap slots. A magnetic flat-head screwdriver & Allen wrench are stored on the bottom of the cage.
• Ergonomic Top Handle: Provides a comfortable grip for easy carrying and low-angle shooting. Features 1/4"-20 threaded holes, 3/8"-16 locating for ARRI holes, and built-in cold shoes for accessories like monitor mounts.
• HDMI Cable Clamp: Mounts to the left side of the cage via a 1/4"-20 screw and two locating pins. Prevents cable deflection and secures cables with a thumbscrew, protecting interfaces and ensuring stable signal transmission. Note: Not compatible with Sony Alpha 1. Interferes with the synchroterminal interface on Alpha 7R V.

Setup and Installation

Follow these steps to properly install your camera into the SmallRig cage:

1. Prepare the Camera: Ensure your camera's lens is removed or is a small enough lens that can pass through the cage opening.

2. Remove Side Locking Pin: Locate the small screw/pin on the side of the cage. Depending on your camera model (Alpha 7 IV or Alpha 7S III/Alpha 1), you may need to switch the position of this pin. Remove it for now.

3. Insert Camera into Cage: Carefully slide your camera into the cage.
4. Secure Bottom Screw: Use the integrated 1/4"-20 screw at the bottom of the cage to secure the camera. Tighten it firmly using the magnetic flat-head screwdriver/Allen wrench stored on the bottom of the cage.
5. Install Side Locking Plate: Re-insert the small pin (removed in step 2) into the camera's strap eyelet on the left side. This pin, along with the side locking plate, prevents the camera from twisting within the cage. Tighten the corresponding screw on the cage to secure it.

   Note: The camera strap eyelet will be occupied when this side locking plate is in use.

6. Verify Battery Access: Ensure that the battery compartment door can still be opened and closed freely with the cage installed. The cage is designed to allow full access.
7. Attach Top Handle: Align the top handle with the mounting points on the top of the cage and secure it using the provided screws.

8. Attach HDMI Cable Clamp: If desired, attach the HDMI cable clamp to the left side of the cage using the 1/4"-20 screw and two locating pins. This helps prevent accidental disconnections and protects the HDMI port.

   Note: This cable clamp is not compatible with Sony Alpha 1 and interferes with the synchroterminal interface when used on the Alpha 7R V camera.
