A huge, 1.8kg ball head that's 16cm tall and 9cm across, this Graf Studioball is designed to hold (one assumes) almost any sort of camera you could imagine. Can't find specs for this, but it's sturdy enough to hold up a second Graf Studioball, so that's something. Light cosmetic wear, good function. Includes original plate with a 3/8" thread- not the small-camera standard 1/4", so be aware that you may need to change out the screw or plate if you have a 1/4" thread on your camera.
