It's a versatile piece of kit. I purchased mine as part of my office studio rig to hold my video camera in a very awkward location. It's a sizable camera and it does the trick nicely. I'm not sure how I would have rigged the camera up the way I wanted it otherwise. I'm very pleased with this arm.
I need 2 others!
Though it is rather large, it does hold well. When used with the Super Clamp, it allows me to get my flashes (StrobePro X200 and Nikon SB-700) where I need them.
Wish I had discovered this item early!
If you need one or two or more don't hesitate to buy it. I bought four. This thing is awesome and very sturdy.
