The Giottos MH-1004 is a great little ballhead. Smooth, easy operation and the ability to provide a surprising amount of holding power in such a small package, it was a natural choice for the TrailPix product. Officially rated for 2 kg/4.4 lbs, you will get maximum life and usability from limiting it's use to cameras about half that heavy. Choose the Kingjue BD-1 for best results with larger cameras, particularly if you do a lot of portrait orientation shooting.
