The Acratech Ultimate Ballhead design allows the macro photographer full range of motion when setting up the framing on your subject.  

They have cut away the from portion on the face of the ballhead so you can move the camera freely into position.

Landscape and wildlife photographers are always shooting straight ahead, but macro photographers are always maneuvering our camera into all kind of different angles and positions to frame our shots, so this head makes our lives a lot easier.

Hunt's Photo has been kind enough to offer a 12% discount on this head. 

Here is a link to the head on sale.
