Great extension

I got a second camera and immediately bought this extension for it. It balances and extends the grip, making the Sony FX3 easier to handle, and it feels secure.

Adds a little stiffness, some stability, ads way more mounting points and looks super cool.

Will the SmallRig Extension Mount Plate Kit for Sony FX3 and FX30 XLR Handle also fit the Sony FX2 handle?
Works fine with FX2 you just won't be able to adjust the angle of the viewfinder.
