Probably the lightest usable ball head

In my broad-based Stativzoo (including Gitzo, Berlebach, Markin, Kirk, FEISOL etc.) occupied the Sirui carbon 10k the role of the lightest serious ball head (as opposed to the various heads which are good for no more than a compact camera) and forms together with the Slik Sprint Mini after some renovation work a full panorama compatible small tripod that weighs in at just 740 grams on the scale:

First of all I unscrewed from the ball the removable disk (need some force!), Filed two "noses" and re-cut the internal thread to 1/4 inch to the head now runs (ball down, rotating plate above and then return to the terminal be able to mount screw) on the tripod with suitable 3/8 inch. As Nodalpunktadapter I use a rail Benro MPB-10 and a RRS L-bracket to the D7000. When I stand, the center column completely removed and replaced by a threaded pin with suitable locknut, thus the weight decreases and increases the stability.

The Sirui C-10k is a very useful small head, which provides between holding power, smoothness of operation, weight and price the best compromise, even or especially in the circles most expensive heads Gansterer manufacturers like Manfrotto, Novoflex or FLM for me.

Full points!
