This Camera Cage from 8Sinn is custom-fit to your Sony a1 mirrorless camera for expanded mounting capabilities while maintaining access to the buttons and controls of the camera. Multiple 1/4"-20 and 3/8"-16 ARRI-style threads allow you to mount accessories like articulating arms and secondary monitors onto the cage.
Your camera secures to the cage via an anti-twist M2.5 screw. The top of the cage has M4 threads for mounting a compatible top handle extension adapter, as well as a cold shoe mount for integration of a wireless transmitter or shotgun microphone. A strap attachment slot allows you to insert a carrying strap of your choice for increased portability.
