1. Introduction
This manual provides instructions for the installation and use of the SmallRig Full Cage with Silicone Side Handle, designed specifically for the Sony A7C camera. This accessory enhances camera handling, protection, and expands mounting options for various photographic and videographic equipment.
2. Key Features
- Enhanced Compatibility: The updated design of cage 3212 improves fit for the Sony A7C, providing increased space in front of the hot shoe for compatibility with microphones like the ECM W2BT and flashes such as the HVL F32M. It also features a broadened dummy battery cable port and a repositioned pin wrist strap hole, eliminating the need to remove the camera strap's triangle loop if the side lock is not used.
- Ergonomic Silicone Grip: An integrated silicone grip offers improved handling and comfort. This grip is removable, allowing for a more compact setup with reduced spacing between the camera body and the cage when removed.
- Redesigned Side Locking Mechanism: The cage secures to the camera via a 1/4"-20 screw at the bottom, complemented by rubber pads to prevent scratches. An additional right side lock, engaged by pressing a slider and attaching a small screw to the camera's strap hole, provides anti-twist stability.
- Multiple Mounting Points: The cage is equipped with various attachment options, including multiple 1/4''-20 threaded holes, 3/8"-16 ARRI locating holes, and a built-in cold shoe. These allow for the attachment of accessories such as top handles, cold shoe extensions, tripods, microphones, and LED lights.
- Integrated Arca-Type Plate: A built-in Arca-type bottom plate enables direct connection to DJI RS 2 / RSC 2 / RS 3 / RS 3 Pro gimbals, facilitating quick transitions between handheld and gimbal shooting.
- Built-in Screwdriver: A convenient screwdriver is integrated into the bottom of the cage for easy installation and removal of camera screws.
