Overall, this is a well made and solid cage. It is great for mounting extra handles and microphones on your camera. But it has one flaw...
I got this cage hoping that I could take my camera easily in and out of the cage, and still mount it on my tripod using the Arca plate. It was not to be.
I have this cage, a Smallrig 2143 Arca clamp, and a Smallrig 2146 quick release plate.
You can't use the 2146 plate in this cage, you must use the included plate. But the included cage-compatible Arca plate is slightly narrower than the 2146 plate. This means that every time you switch from mounting the camera to mounting the cage on your tripod, you need to get out a hex key and re-adjust the 2143 clamp to make it fit. Which makes it anything but "quick release".
I wanted to use a Peak Design Arca Swiss plate so I could use a Peak Design Clutch and I found that the lever tie down only would work with the provided Arca Swiss plate. Taking the Lever system apart, and a careful 5 min of filing on the angled part of the hold down resulted in me being able to use other Parties Arca Swiss plate. I would Give this product a 5 star review If I didn't have to go through that trouble from the get go.
Purchased this with the Arri locating top handle and the Arri rosette wooden side handle. Everything is top quality -- sturdy, solid and aesthetically pleasing.
This configuration — with a small, intermediate arca plate between the camera and the cage — makes much more sense to me than the more conventional camera-mounted-directly-to-cage design. The weight of a full cage can be a disadvantage when switching from a tripod rig to a gimbal, for example, and this approach solves that problem.
I would suggest making the camera plate as thin as is practical, in order to help keep the centre of gravity as low as possible on a gimbal. Also make sure that the base of the cage can be securely mounted on a second arca plate, to make both elements interchangeable.
You might also consider using a square, "bi-directional" arca plate instead of the conventional one illustrated. This would allow the camera to be mounted on both transverse and longitudinal arca clamps, which would be handy in some situations.
Most importantly — please also make a version for the GH5S!
