The head is great, in any position keeps a heavy camera with lens in accordance with the correct installation, so if no gross movement of loads is made. Large lenses should be attached to a Ob.Schelle always in order to balance out the load can. The 23 kg are not the weight of the camera with lens, but the lever load which arises at the ends and acts on the ball! Even wind brings load, as well as an uneven stand way the tripod. The devil is here in the "incl. SK-unit" which ordered no other dimension. The SK unit fits, but ... I will not shake the feeling that is a bit too small, about 0.25 mm on each side. Because of the problems with the attachment with this unit SK I refer to my review when ordering the SK unit. I use the ball head is currently very intense, my hair is already gray, too bad that the head suffers from the SK-unit and my hair can not regenerate.
