One thing to note is that this cage design blocks access to the Sony Multi-function hotshoe just in case you're working with the Sony XLR adapter (seen here). The Shark Cage comes with a Top Handle, 15mm Base, (2) 15mm Aluminum Rods, locks for HDMI and audio cables, and enough room to support various lens adapters.
The Varavon Zeus Cage is available with one handle (standard model), or two handles (premium model), and an extra handle can be purchased separately. Each handle has a modular design that allows it to rotate in 4 different directions, has two cold shoes built in, dozens of threaded mounting options, and incorporates a 15mm rod clamp.
The Zeus cage itself allows full access to all ports and doors and instead of dedicated HDMI or Audio cable locks, Varavon has designed a modular Cable Clamp that can be attached to any threaded mount on the cage or handles.
