SmallRig Cage for Sony a1 II & a9 III Reviews

Great minimalist cage

Fits perfectly, as expected. Adds some needed anchor points to the camera.

Feels great in hand.

I love this cage. The way it wraps around the grip adds a great feel to the camera, and makes the camera much easier to hold with my big hands. Looks great when attached as well. Only negative of the cage would be the lack of any mounting points on the right half of the cage, but for what I need it gets the job done nicely.

Asked by: Kaloma
The SmallRig Cage for Sony a1 II and a9 III Mirrorless Cameras is not a Hawklock cage and does not have any Hawklock mounting points. However, many Hawklock components could be adapted so they attach to the SmallRig 5187 cage.
