I also got a small lens adapter support which can help support lens adapters (which is quite obvious). It doesn’t get in the way even when not using it (it can be adjusted up and down) and will help with heavier or longer adapted lenses when you need it.
You’ll have a range of options when attaching a top handle and I went with a simple metal one with screw mounts all over it. It attaches via a NATO rail with safety locks which you can buy separately (it doesn’t take unnecessary space if you don’t want to use it and it’s extremely cheap if you do). There are also cold shoe attachments on the top and end of the handle for things like a microphone or external monitor/recorder. Of course it’s covered in 1/4-20 and 3/8 mounting points as well as the hole pattern for ARRI accessory mount pins. You can slide the handle back and forth to fit how you want to grip it and also to find a good balance for your particular camera setup. This is done with 2 allen bolts and there is a hex wrench hidden in the handle itself, held in place with a magnet. This is really convenient, especially since it takes up nearly no space. I actually wish they did this for the other allen bolts as well, like in the rail support system (they’re a different size).
Speaking of the rail support system, it has an Arca Swiss quick release plate on top, so you can quickly and easily remove your camera from the rail setup. You could then, of course, attach a plate to the bottom as well so you can remove either the camera only or entire rig from a tripod as easily as you would without any cage or rod setup. I love this design except that the Arca Swiss plate on the bottom of the cage means you’ll have to remove that before you can remove the camera from the cage if you want to do so. Both the plate and the cage attach with regular screws like almost any tripod plate would but the slot in these screws feels a little more shallow than I’m used to. This means it’s a little more difficult to remove with a coin without fear of messing it up. It’s far from impossible and this is really nitpicking but I think the ease of removing these is one area that could be improved. Finally, the rod clamp can slide up and down on this system (with an allen bolt) to match the height of your lens and follow focus/matte box. The rods are fairly standard and are available in multiple lengths, diameters and of course aluminum or carbon fiber. The ends of the rods are threaded so you can extend them if you wish.
With a few very minor complaints such as wanting another hidden hex wrench or easier-to-remove screws in the quick release plate and bottom of the cage, this setup is extremely solid. There’s not a whole lot to say besides the facts because it just works. As with any rig, you could spend hours and hours designing and laying out your rig, but SmallRig will always allow you to do just what you want. It has a very heavy duty feel for a not heavy duty price and the limits will be only in your imagination.
