I ordered my arm to photograph objects in addition to the tripod axis, eg on a table can. The arm is very stable and has 4 Anschlussmöglichkeiten.2x 1/4 "at the ends and 2x3 / 8" to be mounted on the movable and tiltable Schlitten.Um a camera or a compact flash unit on one of the carriages, must therefore again a ball head "interposed "werden.Aufgrund the 3/8" thread must for a flash unit, a relatively large head sein.Besser here would be an opportunity between the thread sizes to change. Who does not interfere with this limitation, gets a very stable part, which requires a very sturdy tripod as a substructure. I have returned the arm.
