The monoballPan System 2 from Arca-Swiss allows for ample movement and rigid fastening when doing panoramic photography with medium format cameras, large zoom SLRs, as well as very long focal length lenses. The profile of the rails provide vibration-free shooting while the camera is in a vertical orientation. It is compatible with monoballFix quickset devices or monoballclassic quickset devices with an adapter.
Note:
For accurate panoramic use, the ability to move your camera along the Z axis in order to adjust the nodal point in two dimensions, a separately-sold nodalSet is required. These include B&H # ARNMBC, ARNMBFL, or ARNMB.
