Do you work with a few different camera bodies and need a universal cage to fit them all? Perhaps you've upgraded camera bodies and your old Cages is no longer compatible with the new camera body? Or maybe you just have one of those camera bodies that don't third-party companies choose not to make dedicated cages for (i.e. Sony RX10MKII, Panasonic G7, etc.).
Situations like these are probably good reason to look at the new Varavon Zeus UNI C-Type Half Cage. It's designed to fit around most camera bodies giving you a proper Top Handle and dozens of mounting points for your EVFs, Monitors, Microphones, LED Lighting, etc. The video below offers a look at the Varavon Zeus UNI and a general idea how it works.
The Varavon Zeus UNI seems to be versatile enough to work with many different camera bodies, but there could be times when the cage blocks the top dials. This is mainly an issue with cameras that are very flat at the top. But with cameras that have slightly raised hotshoes (GH4, A7sII, Canon 5D, etc) this will provide additional clearance to access those top dials and menu buttons.
I believe most people would rather choose a custom designed form fitting Cage for their camera bodies. But if you can't seem to find one available for your unique camera model, this simple C-Type Half Cage could be a great option. For more information visit the Zeus UNI product page (here).
