I bought this as a way to attach my camera to the pole on an older enlarger so that I could make copy stand for 'scanning' 35mm and 120 negative film. Due to the size and surface of the enlarger stand, I found that the clamp's grip wasn't quite as solid as I'd have liked, but after a couple of months trial I have found that the camera is stable for my purposes. For transparency, I'm holding a Fuji XT2 camera with 7Artisans 60/2.8 macro lens with the clamp, set so that the clamp is holding the camera and lens at right angles to the baseboard. This is probably the most demanding angle that you could use the clamp for, and whilst there is a little play, it doesn't slip and since I'm using a remote release cable there is no danger of accidentally moving it out of alignment. I'm not sure about the 5Kg maximum loading claim under these particular circumstances, but for most purposes I think it would be fine. I like the concept and it appears to be quite well executed but is not quite the 'super clamp' system I'd hoped for, but in practice is doing the job. My original review was a little more critical but in hindsight since I got it to work for me I'm satisfied and an update was appropriate.
