The Acratech GP Ballhead is not only a first-class ballhead, it can also function as a gimbal head for shooting with telephoto lenses, and even be used upside down as a leveling base for stitched panoramic images. The GP Ballhead makes it possible for you to pan parallel to the horizon, even on very rough terrain, so there's no need for a separate leveling base for accurate panoramic images. All of this, and it only weighs 1 lb. It also includes a quick release clamp with bullseye level, double-speed knob and detent pin (which prevents the plate and anything attached to it from sliding out of the quick-release clamp when it's partially loosened).
