The SmallRig 5591 half-camera cage for the Sony FX2 provides essential protection while allowing for extensive accessory expansion for professional videography workflows. This lightweight aluminum construction features a secure 2-point locking system that ensures full access to all camera ports, including the tiltable EVF, control buttons, and input/output connections. The integrated Arca-Swiss quick-release plate at the base allows for quick transitions between handheld operation, tripod mounting, and compatibility with DJI RS 2, RSC 2, RS 3, RS 3 Pro, RS 4, and RS 4 Pro gimbal stabilizers. A removable top plate includes a NATO rail that can accommodate both Sony's XLR top handle and SmallRig's rotating top handle without obstructing the electronic viewfinder. Multiple mounting options include 1/4-inch-20 threaded holes, 3/8-inch-16 ARRI locator holes, and a HawkLock NATO rail system for quick attachment of side handles and top handles. Additional features include a cold shoe for accessories like the DJI Mic 2 or LED lighting, a QD socket for shoulder strap attachment, and strap loops for enhanced portability. The lower quick-release plate is compatible with the HawkLock H38 Arca-Swiss quick-release mounting plate for fast insertion with automatic locking. An integrated magnetic Allen key in the base provides convenient tool storage for mounting and dismounting. This half-cage maintains compatibility with the SmallRig HawkLock accessory ecosystem while ensuring complete access to all camera functions and connections.
