I'm really excited about this Magic Arm Set from K&F Concept after playing around with it a bit! Great set, super versatile
Here you get a “Magic Arm” with a joint in the middle and two ball joints with 1/4 inch screws at both ends, as well as a smartphone holder and a clamp (for handlebars etc.).
There is nothing wrong with the quality of materials and workmanship. The parts are made of metal, the smartphone holder is made of plastic, and the metal parts look really good and valuable in their anodization, I hope that it stays that way for some time. The smartphone holder also looks very high-quality and significantly better than most of what you get “like that” in various sets. Top!
The smartphone holder is very easy to use and really of good quality. In addition to two 1/4 inch screw sockets, it also has a holder for a hot shoe adapter, as many cameras also have. It's a better kind of smartphone holder, definitely!
There is also nothing wrong with the clamp for handlebars and pipes. Rubber protects the surface and makes the whole thing slip-resistant. The wing screw is very good and easy to use. This clamp has two threads for both screw sizes common in photography: A 1/4 inch thread and a 3/8 inch thread for the larger screws. Very good, I'm really impressed.
But the highlight is probably the “Magic Arm”. I had to play around for a while to understand how the system worked. The two ball heads at the ends of the double arm (which can be tilted up to 90°) do not have their own screw mechanism for fixing, but are fixed together with the knee joint that connects the two arms. This central joint can only be adjusted in one plane and the position is fixed by means of a wing screw. But the joint also has “grids”, so the adjustment is not completely continuous (but almost). With the central joint, however, the two ball joints are now also fixed at the ends, via an invisible mechanism. The farther the wing screw is turned on, the tighter both ball joints sit at the ends (always equally tight), up to “bomb-proof”. The adjustment works better than expected, because when the wing screw is screwed in, the central joint is first fixed due to the “latching”, while the two end ball joints can still be moved in the ball head sockets, depending on the degree of fixation in the middle. This allows you to adjust the entire arm really well, first the middle position, then the two ends, and the “strength” when adjusting (the resistance of the balls in the pans) can be adjusted continuously using the wing screw. When all three joints are in the desired position, the central wing screw is tightened and everything is absolutely tight. If you want to adjust one of the ball joints a bit more, turn on the screw slightly, align the joint (against the resistance), and screw it tight again.
Great system, I'm really impressed!
Overall, a great set from K&F Concept, not even my first product from this brand in the photo accessories sector. I'm more than satisfied, the price is really good in my opinion.
Recommendation!
