About SmallRig 4538

The SmallRig HawkLock Quick Release Cage Kit for Sony Alpha 7R V, Alpha 7 IV, and Alpha 7S III (model 4538) is expertly designed to enhance your shooting experience by facilitating low-angle shots while providing robust protection for your camera. This comprehensive kit includes a durable cage, an HDMI cable clamp, a NATO rail, and a top handle, all engineered to offer a multitude of accessory mounting options.

The standout feature of this kit is the patented HawkLock quick-release structure, which integrates cold shoes, NATO rail, and Arca-Swiss compatibility. This innovative system, when used with HawkLock eco-accessories, ensures a secure fit with no false positioning, allowing for quick loading and locking with a single push, thereby significantly improving disassembly efficiency.

The ergonomically designed top handle provides a comfortable grip, making it easier to carry your camera and capture dynamic low-angle shots. The cage is equipped with 1/4"-20 threaded holes, ARRI 3/8"-16 locating holes, cold shoes, and NATO rails, offering extensive support for mounting monitors, microphones, LED lights, and other NATO accessories. The HDMI cable clamp, attached to the left side of the cage with a 1/4"-20 screw, prevents cable deflection and secures connections with a thumbscrew, ensuring stable signal transmission and protecting your camera's interfaces.

For added convenience, the cage includes a built-in magnetic flat-head screwdriver and hex spanner, facilitating easy assembly and disassembly. The design also features strategically placed holes on both sides for attaching hand straps, enhancing portability and security.

Engineered with precision, the cage boasts a 3-point locking system and anti-slip silicone pads, providing amplified stability and safety for your camera. The internal roll pins maintain suspension during disassembly, ensuring a smooth, frictionless experience with zero wear. The multi-slot design allows for precise adjustment and consistent positioning, even with repeated use.

Crafted from sturdy, scratch-resistant aluminum alloy, the cage features a premium color combination of regal hawk gray, midnight black, and shimmering silver, with a delicate metallic finish. The CNC precision machining ensures standardized accuracy control within 0.05-0.10mm (0.002-0.004in), delivering optimal precision and a perfect fit.

Compatible with both new and old NATO clamps and Arca-type accessories, this cage eliminates the need for additional purchases. The built-in Arca-Swiss quick release plate at the bottom allows for seamless transitions between tripods and stabilizers.

Note: After securing the 1/4"-20 screw at the bottom of the cage, remove the anti-deflection pin from the staging hole in the battery compartment and fix it to the corresponding position. To utilize the side lock adapter, remove the split ring on the left side of the camera first. Please be aware that the HDMI cable clamp may interfere with the synchro terminal interface when used with the Alpha 7R V camera.
